Last updated: 10 November 2026
1. Seller
The website wallnia.com is operated by ALIX GROUP SRL (private limited company), trading as Wallnia, with registered office at Rue Saint-Valentin 142A/021, 6061 Montignies-sur-Sambre (Charleroi), Belgium, registered with the Crossroads Bank for Enterprises under number 0880.314.689, VAT BE 0880.314.689. Email: kerimali0961@gmail.com. Phone / WhatsApp: +32 486 33 91 40. Hereinafter “Wallnia”.
2. Scope
These general terms and conditions of sale apply to every order placed on wallnia.com by a consumer or a business. By confirming the order, the customer declares that they have read and accepted them.
3. Products
Wallnia sells made-to-measure printed wallpaper (repeating patterns and panoramic murals), as well as accessories such as paste. The photos and previews on the website are representations: slight differences in colour may exist between the screen and the print, depending on the screen used and the material.
4. Orders and dimensions
The customer enters the width and height of their wall, chooses the material, then checks the preview of their wallpaper. The customer is solely responsible for the accuracy of the dimensions entered; we recommend adding a 5 cm margin to the width and height (see the measuring guide). The contract is concluded when the order confirmation email is received.
5. Prices
Prices are shown in euros, including all taxes. Wallpaper is charged at the displayed price per m², based on the wall area rounded up to the nearest 0.1 m², with a minimum order of 1.5 m². The total price is shown before the order is confirmed. Any delivery costs are shown before payment.
6. Payment
Payment is made online when ordering, using the payment methods offered at checkout. The order goes into production once payment has been confirmed.
7. Production and delivery
Each wallpaper is printed after the order is placed. Delivery terms, areas and times are set out in our shipping policy. Unless otherwise agreed, delivery takes place no later than 30 days after the contract is concluded.
8. Right of withdrawal
As the wallpaper is made to the customer’s specifications, it is excluded from the right of withdrawal (Article VI.53, 3° of the Belgian Code of Economic Law). Standard, non-personalised items can be returned within 14 days. Full details are set out in our returns policy.
9. Reprinting a damaged part and legal guarantee
If the wallpaper received has a printing defect, or if a panel or the parcel is damaged, the customer reports it with photos within 14 days of receipt and before hanging. After reviewing the photos, Wallnia reprints the affected part free of charge, including delivery.
Colours may vary slightly between the screen and the printed wallpaper, depending on the screen used and the material. These slight variations are not a defect and do not entitle the customer to a reprint.
This commitment is in addition to the 2-year legal guarantee of conformity to which consumers are entitled; it does not limit it in any way.
10. Hanging
Hanging is carried out by the customer or by a professional of their choice, under their responsibility, following our hanging guide. Wallnia cannot be held liable for damage resulting from incorrect hanging or an unsuitable surface (damp, unprepared wall, etc.).
11. Intellectual property
Wallnia designs, texts, images and website content are protected. Any reproduction without written permission is prohibited. Buying a wallpaper does not grant any right to reproduce the pattern.
12. Personal data
The processing of personal data is described in our privacy policy.
13. Disputes and governing law
These terms are governed by Belgian law. If a problem arises, please contact us first so that we can find an amicable solution. Consumers can also contact the Belgian Consumer Mediation Service free of charge (consumentenombudsdienst.be). Failing agreement, the courts designated by law have jurisdiction; consumers retain the protection of the mandatory rules of their country of residence.
