General Terms and Conditions of Sale

These General Terms and Conditions of Sale (the "Terms") govern every contract for the sale of goods concluded through korena.eu (the "Site") between "Martial Labs" Ltd. trading as KORENA (the "Seller", "we", "us") and any buyer placing an order on the Site (the "Buyer", "you").

By placing an order you confirm that you have read, understood and accepted these Terms.

Quick read: KORENA is a brand of "Martial Labs" Ltd. (Маршъл Лабс ЕООД), a Bulgarian company, EIK 207453941, VAT BG207453941. We sell premium hardwood slabs across the EU. Each slab is a unique, individually photographed and measured piece. Consumers have a 14-day right of withdrawal (with carve-outs for custom-cut pieces) and a 2-year legal guarantee. Businesses contract on the additional terms in §11. Bulgarian law applies. EU Online Dispute Resolution: ec.europa.eu/consumers/odr.

1. Definitions

In these Terms:

  • "Consumer" means a natural person acting for purposes outside their trade, business, craft or profession, within the meaning of the EU Consumer Rights Directive 2011/83/EU and the Bulgarian Consumer Protection Act.
  • "Business Buyer" means any Buyer that is not a Consumer. This includes: (a) sole traders and self-employed persons making a purchase in connection with their trade, business, craft or profession; (b) companies, partnerships, and other legal entities; (c) public bodies. A natural person (including a sole trader) who purchases for personal use, domestic consumption, or private purposes remains a Consumer regardless of VAT-registration status.
  • "Goods" means the hardwood slabs, boards, processing add-ons, and related items offered for sale on the Site.
  • "Order" means a binding offer by the Buyer to purchase one or more Goods at the price and on the terms displayed on the Site at the time of submission.
  • "Contract" means the agreement formed when we accept an Order in accordance with §3.
  • "Capture Bundle" means the structured measurement record (polygon outline, dimensions, photos, moisture reading at listing, where present) attached to each piece, generated by our KORENA Capture iOS application and described in the listing.
  • "Partner Yard" means a third-party hardwood yard or sawmill at which physical Goods are stored before sale; the Partner Yard is our supplier under a separate consignment arrangement and is not a counterparty to the Buyer.
  • "Slab" means an individual premium hardwood plank or board offered for sale on the Site, including any processing add-ons commissioned by the Buyer.
  • "Listing" means the product display on the Site for a Goods, including the mandatory photo set and the Capture Bundle.
  • "Photo-Set Description" means the mandatory multi-photo catalogue (raw finish, wet-wiped, backlit edge, end-grain, ruler-in-frame, defects close-ups) that forms part of the binding description of the Goods.
  • "Trader" means "Martial Labs" Ltd. trading as KORENA, the legal person offering Goods for sale on the Site.
  • "Withdrawal" means the Consumer's exercise of the right to terminate the Contract within 14 days under EU Consumer Rights Directive Art. 15, on grounds of change of mind and not defect.
  • "Statutory Warranty" means the two-year legal guarantee of conformity under EU Sale of Goods Directive 2019/771, transposed into Bulgarian law, applying to Consumers only.

2. Identity of the Seller

The Seller is fully identified in our Legal Notice / Imprint. "Martial Labs" Ltd. is the seller of record for every Order placed on the Site. Although Goods are stored at Partner Yards until shipment, the Buyer's contract and every right and obligation under it run between the Buyer and "Martial Labs" Ltd. only.

3. Order process and contract formation

3.1. Listings on the Site are an invitation to treat, not a binding offer. Submitting an Order constitutes the Buyer's binding offer to purchase.

3.2. We reserve the right to refuse or limit any Order at our discretion before payment is captured, including (without limitation) where stock has become unavailable, where we suspect fraud, where shipping to the Buyer's address is not feasible, or where pricing was displayed in error.

3.3. Contract formation and order confirmation. The Contract is formed at the earlier of (a) our sending of an Order Confirmation email accepting the Order, or (b) capture of payment from the Buyer's payment method. An automated "we received your Order" acknowledgement is not, by itself, acceptance. On acceptance, we send the Buyer an Order Confirmation by email on a durable medium. The Order Confirmation contains the information required by Article 6 of the EU Consumer Rights Directive: the Goods, quantity, unit price and total price (including taxes and shipping), delivery terms and lead time, our identity and contact details, withdrawal information including the Annex I model withdrawal form, the existence and duration of the legal guarantee of conformity, the means of redress, and a copy of these Terms, the Withdrawal Policy, the Returns & Warranty Policy, and the Shipping Policy.

3.4. Each slab listed on the Site is a unique piece. Once an Order for a slab is in process, that slab is taken offline and cannot be ordered by another Buyer.

3.5. Stock reservation. Adding a slab to cart places a soft reservation for ten (10) minutes. Beginning checkout extends the reservation to twenty (20) minutes. On payment authorisation the reservation becomes a hard hold until shipment.

3.6. Order errors. The Buyer is responsible for the accuracy of the data provided in the Order (delivery address, VAT ID, contact details). We will rely on that data to perform the Contract.

3.7. Order submission button. At the moment of final order submission, the Buyer activates a button labelled "Order with obligation to pay" (Bulgarian: "Поръчай със задължение за плащане") or an unambiguous equivalent in the active language. Clicking that button constitutes the Buyer's binding offer referred to in §3.1. A submission via any other button label or mechanism does not constitute a binding offer.

3.8. Pre-authorisation notice. We may pre-authorise the Buyer's payment method at checkout to verify validity. The pre-authorisation may show on the Buyer's bank or card statement as a debit or hold before the Order is accepted under §3.3. If we do not accept the Order, the pre-authorisation is voided within five (5) Business Days; voiding may take additional time to reflect on the bank or card statement depending on the financial institution.

3.9. Right of withdrawal: approximate return cost (Consumer Buyers only). If you are a Consumer Buyer, you have the right to withdraw from this Contract within 14 days at no cost, except that you are liable for the cost of returning the Goods to us. Because slabs are heavy and palletised goods, return costs are not negligible. For your transparency before you are bound by this Contract, the approximate return-shipping cost for oversize or freight slabs typically falls within the range of EUR 80–500 depending on your destination, the slab's weight and dimensions, and the carrier chosen. A binding quote will be provided on request before you confirm the return shipment. See the Withdrawal Policy §6 for full details on withdrawal, return-shipping arrangements, and how we can help you find the most economical option.

4. Pricing, taxes, and invoicing

4.1. All prices on the Site are quoted in Euro (EUR).

4.2. For Consumers, prices on listing pages and at checkout are inclusive of VAT at the applicable rate. Bulgarian VAT (20%) applies to deliveries within Bulgaria. Cross-border B2C deliveries within the EU are taxed under the EU One-Stop Shop (OSS) regime in line with the destination country's VAT rate, where required by law.

4.3. For Business Buyers with a valid EU VAT identification number entered at checkout, deliveries to other EU member states are invoiced under the reverse charge mechanism (Article 196 of EU VAT Directive 2006/112/EC); the invoice will be issued without Bulgarian VAT and the Business Buyer is responsible for accounting for VAT in its country of establishment. Domestic Bulgarian B2B deliveries are invoiced with 20% Bulgarian VAT.

4.4. Shipping costs, customs duties (where applicable, e.g., EU → non-EU territories that we may serve in the future), and any optional processing fees are shown separately at checkout before payment.

4.5. Manifest pricing errors. Where a price displayed for a Slab is so plainly mistaken that no reasonable consumer would have relied on it (for example, two orders of magnitude lower than the comparable retail price for similar species, thickness, and dimensions), we may cancel the Order before delivery and refund any payment in full within five (5) Business Days. We do not invoke this clause for ordinary pricing variation or competitive pricing decisions.

4.6. Invoice. We issue an electronic invoice for every Order in accordance with Bulgarian VAT and accounting rules. The Buyer accepts the issuance of invoices in electronic form by accepting these Terms.

4.7. Reference price on reductions. Where a price reduction is displayed for a Slab, we display alongside it the lowest price at which that Slab was offered to the public during the 30 days preceding the reduction, in accordance with Article 6a of Directive 98/6/EC (Price Indication Directive).

4.8. Trader disclosure. "Martial Labs" Ltd. trading as KORENA is the trader offering Goods for sale on the Site. Every listing is offered by this single trader; no third-party seller listings are hosted on the Site.

4.9. Ranking parameters and transparency. Where ranking parameters are applied to listings on the Site (default sort order, recommendations, search result ranking), the main parameters influencing the ranking and their relative weight are disclosed at the point of display, in accordance with the Omnibus Directive 2019/2161 amendments to Article 7 of the Unfair Commercial Practices Directive 2005/29/EC.

5. Payment

5.1. Payment is collected via Stripe at checkout. Accepted payment methods are those displayed on the checkout page at the time of Order. Stripe is our payment processor and a separate data controller for the payment data; see our Privacy Policy.

5.2. Authorisation and capture. We typically authorise the payment method at checkout and capture funds upon confirmation that the Goods are reserved at the Partner Yard, normally within 24 hours. If we cannot confirm the slab and ship it, we will void the authorisation and no charge is made.

5.3. Failed payment. If a payment fails or is reversed after the Order is accepted, the Contract is automatically suspended; if payment is not successfully completed within five (5) Business Days, the Contract is rescinded and the slab is returned to the catalogue.

5.4. Bank transfer (B2B only). For Business Buyers, on request we may accept payment by bank transfer to the IBAN listed in our Imprint. Goods will not be released for shipment until cleared funds are received. Bank transfer fees are borne by the Business Buyer.

6. Delivery, risk and title

6.1. Delivery terms, lead times, carriers and freight pricing are described in the Shipping & Delivery Policy, which is incorporated into these Terms by reference.

6.2. Risk of loss:

  • For Consumers, the risk of loss or damage to the Goods passes on physical delivery of the Goods to the Consumer or to a person nominated by the Consumer (other than the carrier we have arranged), in accordance with EU Consumer Rights Directive 2011/83/EU Art. 20.
  • For Business Buyers, the risk of loss or damage to the Goods passes on handover of the Goods to the first carrier, in accordance with the default rule of Bulgarian commercial law.

6.3. Title. Title to the Goods passes to the Buyer upon full receipt of payment by us and delivery, whichever is later.

6.4. Delivery delays and Consumer remedies. Stated lead times are estimates. Where we fail to deliver within the lead time stated at Order, the Consumer may set an additional period of delivery appropriate to the circumstances, in accordance with EU Consumer Rights Directive Art. 18(2). If we fail to deliver within that additional period, the Consumer may terminate the Contract and receive a full refund within fourteen (14) days. Force majeure events (§14) suspend lead-time clocks but do not disapply the Consumer's right to set an additional period and terminate.

7. Conformity and what each slab actually is

This section is the most important read for any Buyer new to buying live-edge hardwood slabs sight-unseen.

7.1. Each slab is a unique, individual piece. The photos, polygon outline, dimensions, weight, moisture reading and any other data shown on the listing relate to that specific physical slab at the time of capture. They do not represent a class of goods and are not "examples".

7.2. Measurement. Each listing's dimensions are generated by our KORENA Capture system from a photographed, measured outline of that specific slab at the time of capture. The measured values are the dimensions of that slab; we do not guarantee any measurement beyond the values shown. The Capture Bundle is preserved as evidence.

7.3. Wood is a natural material. The following are characteristics of the product, not defects:

  • Variation in colour, figure, grain pattern, sapwood ratio, and live-edge profile compared to digital photos viewed on different displays;
  • Natural inclusions, knots, mineral streaks, end-checks, and pin-holes that are visible in the listing photos;
  • Movement in response to ambient humidity, including small dimensional changes (typically up to ±1% across the grain at typical indoor humidity ranges);
  • Changes in moisture content between capture and delivery, typically up to ±2 percentage points relative to the moisture reading shown on the listing.

7.4. Disclosed in photos = disclosed in the Contract. The mandatory photo set for each listing (raw, wet-wiped, backlit edge, end-grain, ruler-in-frame, defects close-ups) is part of the description of the Goods. A characteristic visible in those photos cannot be a basis for a non-conformity claim. This rule applies only where the Buyer has been presented with the complete photo set in the order flow before submitting the Order.

7.5. Custom and processed Goods. Where the Buyer commissions processing add-ons (flattening, planing, cut-to-list, bookmatch pairing, crating) or any cut to specification before shipment, the resulting Goods are personalised to the Buyer's specification within the meaning of EU Consumer Rights Directive 2011/83/EU Art. 16(c) and are not subject to the right of withdrawal under §10. They remain subject to the legal guarantee under §8.

8.1. Consumers. Consumer Buyers benefit from the two-year legal guarantee of conformity under EU Sale of Goods Directive 2019/771, as transposed into Bulgarian law. Nothing in these Terms or in our Returns & Warranty Policy limits or excludes that guarantee, and any provision that purports to do so is severed and read down to the minimum extent necessary.

8.2. Business Buyers. For Business Buyers, the legal guarantee of conformity does not apply by operation of law. We provide a commercial warranty of conformity for thirty (30) days from delivery against material structural defects undisclosed at the time of sale, on the same operational terms as set out in the Returns & Warranty Policy. Beyond that, the Goods are sold "as inspected": Business Buyers are deemed to have inspected the Goods through the photo set, dimensions, and Capture Bundle prior to ordering. All other warranties (express, implied, statutory) are excluded to the maximum extent permitted by law.

8.3. The detailed return process, eligibility, restocking, and refund mechanics are set out in the Returns & Warranty Policy, which is incorporated into these Terms by reference.

9. Damage in transit

9.1. The Buyer must inspect the Goods on delivery and:

  • Sign the delivery note as "received with reservation, damaged" (or local equivalent) if the packaging is visibly damaged;
  • Photograph the packaging and the Goods on receipt;
  • Notify us at office@korena.eu within forty-eight (48) hours of delivery, attaching the photographs.

9.2. For Consumers, failure to follow §9.1 does not, by itself, defeat or extinguish a claim for transit damage under the legal guarantee. We will assess the claim on the basis of available evidence, including the original Capture Bundle, any photos provided, the delivery note, and the Consumer's description. The §9.1 steps are the strongest evidence for a claim against the carrier; we recommend them, but their absence does not bar the Consumer's remedy under the statutory warranty.

9.3. For Business Buyers, failure to follow §9.1 forfeits the right to claim for transit damage, except where the damage was reasonably undiscoverable on cursory inspection and is reported within five (5) Business Days.

10. Right of withdrawal (Consumers)

10.1. Consumer Buyers have a fourteen-day right of withdrawal under EU Consumer Rights Directive 2011/83/EU. The full terms, the Annex I model withdrawal form, and the carve-outs (notably for processed and custom-cut Goods) are set out in the Right of Withdrawal Policy, which is incorporated into these Terms by reference.

10.2. Business Buyers do not have a statutory right of withdrawal.

11. Additional terms for Business Buyers

The following additional terms apply where the Buyer is a Business Buyer. They are in addition to, and prevail over, any other provision of these Terms in case of conflict.

11.1. Business Buyer classification. We treat a Buyer as a Business Buyer where the Buyer (a) provides a valid EU VAT identification number at checkout and (b) places the Order in connection with their trade, business, craft, or profession. The VAT ID is a rebuttable indicator only. Where the Buyer subsequently demonstrates the Order was placed for a purpose outside their trade, business, craft, or profession (e.g., personal consumption or domestic use), Consumer protections under EU and Bulgarian law apply, regardless of the VAT-ID flag at checkout.

11.2. Acceptance and inspection. Business Buyers shall inspect the Goods within five (5) Business Days of delivery and notify us in writing of any non-conformity within that period. Goods not so notified are deemed accepted.

11.3. Limitation of liability. Subject to §11.5, our total aggregate liability to a Business Buyer under or in connection with the Contract, whether in contract, tort (including negligence), breach of statutory duty or otherwise, is limited to the amount paid by the Business Buyer for the Goods that gave rise to the claim. We are not liable to Business Buyers for any indirect, incidental, consequential, special or exemplary damages, including loss of profit, loss of business, loss of contracts, loss of goodwill, or loss of anticipated savings.

11.4. Late payment. Where payment is made by bank transfer rather than at checkout, late payment attracts statutory default interest at the rate set under the Bulgarian Law on Obligations and Contracts Art. 86 (currently the Bulgarian National Bank base rate plus 10 percentage points) and EU Late Payment Directive 2011/7/EU, whichever is higher.

11.5. Carve-outs from limitation. Nothing in §11.3 excludes or limits our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) gross negligence (груба небрежност); (d) any other liability that cannot be excluded or limited under applicable law.

11.6. Resale and Partner-Yard contact. The Business Buyer may resell the Goods in the ordinary course of its business. The Business Buyer shall not, however, attempt to identify, contact, or transact directly with the Partner Yard at which the Goods were stored, whether to obtain a discount, source comparable goods, or otherwise circumvent KORENA. Breach of this clause entitles us to terminate the Contract, recover any pricing concessions granted on the basis of platform-exclusive supply, and refuse future Orders from the Business Buyer.

12. Acceptable use of the Site

The Buyer's use of the Site is also subject to the Acceptable Use Policy, which forms part of these Terms.

13. Personal data

We process personal data in connection with Orders in accordance with the Privacy Policy. The Privacy Policy describes the categories of data we process, the lawful bases on which we process them, our subprocessors (Stripe, Speedy, Econt, Resend, Supabase, hosting), and the Buyer's rights under the GDPR.

14. Force majeure

Neither party is liable for failure or delay in performing any obligation under the Contract (other than payment of price already due) where the failure or delay is caused by an event beyond that party's reasonable control, including without limitation acts of God, fire, flood, severe weather, epidemic, pandemic, war, civil unrest, terrorism, embargo, governmental action, labour dispute, failure of utilities, or carrier failure. The affected party shall notify the other promptly and use reasonable efforts to mitigate.

15. Intellectual property

15.1. The Buyer acquires title to the physical Goods on delivery; the Buyer does not acquire any rights in the photographs, polygon outlines, dimensions, Capture Bundles, descriptions, software, trade marks, or other intellectual property associated with the listing or the Site.

15.2. The Buyer may use listing photographs of the specific Goods purchased for the Buyer's own non-commercial display (e.g., social-media post showing the new dining-table material) with attribution to KORENA. Resale, sublicensing, or use to advertise competing goods is not permitted.

15.3. The detailed rules on ownership, licensing, AI/ML use, IP takedown, and counter-notice procedure are set out in the Intellectual Property & Content Policy, which is incorporated into these Terms by reference and prevails over this §15 to the extent it grants the Operator broader rights or the Buyer clearer rights.

16. Changes to these Terms

16.1. We may amend these Terms at any time, with effect for future Orders. The version in force at the moment the Order is placed is the version that governs that Order.

16.2. Where an amendment to these Terms materially affects the rights of an existing Consumer customer (e.g., a registered account holder), we will notify the Consumer by email at least thirty (30) days before the change takes effect, and the Consumer may close the account before the change takes effect.

17. Communications

17.1. Communications from us to the Buyer are sent to the email address provided at the time of Order. The Buyer is responsible for keeping that email address current.

17.2. Communications from the Buyer to us should be sent to office@korena.eu for general inquiries, returns, and support. For legal correspondence, send to office@korena.eu. (Note: all channels currently route to a monitored mailbox managed by "Martial Labs" Ltd.)

18. Dispute resolution

18.1. Informal resolution. The Buyer agrees to contact us at office@korena.eu before initiating any formal dispute. We will respond in good faith within fourteen (14) calendar days.

18.2. Dispute resolution procedures. Consumer Buyers resident in the EU may use the European Commission's Online Dispute Resolution platform at ec.europa.eu/consumers/odr. KORENA is not currently bound by, and has not voluntarily committed to, any specific ADR body. Bulgarian Consumers may file a complaint with the Bulgarian Commission for Consumer Protection (Комисия за защита на потребителите, КЗП) at kzp.bg. Where we voluntarily designate an ADR body in future, this section will be updated and notice given to the Consumer.

19. Governing law and jurisdiction

19.1. These Terms and any Contract formed under them are governed by Bulgarian law, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG).

19.2. Consumers. Where the Buyer is a Consumer, mandatory consumer-protection rules of the Consumer's country of habitual residence within the EU continue to apply, and the Consumer retains the right to bring proceedings in the courts of that country, in accordance with Regulation (EU) 1215/2012 (Brussels Ia) and Regulation (EC) 593/2008 (Rome I). A Consumer may also bring proceedings against us in the courts of Sofia, Bulgaria, at the Consumer's election.

19.3. Business Buyers. The competent courts in Sofia, Republic of Bulgaria, have exclusive jurisdiction over disputes between us and a Business Buyer under or in connection with these Terms or any Contract formed under them.

20. Severability and entire agreement

20.1. If any provision of these Terms is held to be invalid, illegal, or unenforceable, that provision shall be severed and the remaining provisions shall continue in force. Where the severed provision concerns a Consumer right, the Terms shall be read as if it had been replaced by the corresponding mandatory rule of applicable consumer-protection law.

20.2. These Terms, together with the documents incorporated by reference (the Imprint, Privacy Policy, Cookie Policy, Shipping Policy, Returns & Warranty Policy, Right of Withdrawal Policy, Acceptable Use Policy, and Intellectual Property & Content Policy), constitute the entire agreement between the parties in respect of the subject matter and supersede all prior representations, except (in the case of a Consumer) any pre-contract information that the Consumer reasonably relied on.

21. Languages and binding versions

21.1. These Terms are authored in English, which is the working source of truth.

21.2. Translations may be made available on the Site, including a Bulgarian version. Where the Buyer has a Bulgarian delivery address, the Bulgarian translation is the binding version. For all other Buyers, the English version is binding.

21.3. In the event of any discrepancy between language versions, the version identified as binding under §21.2 prevails.

21.4. Bulgarian consumer pre-contract information. For Consumers with a Bulgarian delivery address, the pre-contract information required by Article 49 of the Bulgarian Consumer Protection Act is presented in the Bulgarian language at every step of the purchase flow (product page, cart, checkout, confirmation), regardless of the active interface language setting. A Bulgarian translation of these Terms, the Withdrawal Policy, and the Returns & Warranty Policy, certified by a sworn translator, is provided with the Order Confirmation and is binding for such Consumers.
