Must be requested within 30 days of receipt of product. All returns must be undamaged in original packaging. We include a sample strip for you to test before opening the 50-foot spools. We recommend testing the sample piece prior to unspooling the 50-foot spools, as any product used from returned 50-foot spools will be deducted from the purchase price at $1.50 per lineal foot. Large spools must be shipped back in the same condition in which you received them, undamaged, adhesive liner intact, spooled, and in the same packaging in which it was received. Customers are responsible for the cost of the return postage.
