Frequently asked questions
Can I order less than a full roll?
Yes — every fabric can be cut to length from one metre at the listed price, with no cutting surcharge. A full roll (50–70 m of fabric, 100 m of reflective tape) is the better deal for production runs: trade accounts get individual roll and volume pricing.
How long does delivery take?
Orders ship from warehouse stock in Poland, Romania and Portugal: 1–2 business days within Poland, 2–7 business days across the EU, 4–10 outside it. Orders of €100 or more (incl. VAT) ship free to every EU country.
Do the prices include VAT?
Catalogue prices are shown ex-VAT, because the correct rate depends on who is buying and where the order ships from. Checkout shows the exact VAT for your order before you pay — EU businesses with a valid VAT number buy cross-border at 0% under reverse charge.
Is the stock reserved once I order?
Yes. The moment you place an order, the quantity is booked for you in the warehouse for seven days — time enough to arrange payment and paperwork. Availability shown on this page is live warehouse stock.
Can I return fabric?
Uncut rolls and packed accessories — yes, consumers have the statutory 14-day withdrawal right. Fabric cut to your metreage is exempt by EU law (it is cut for you from a larger roll), so order a test metre first if you need to verify the material. Details in the returns guide.
