The vinyl sticker consists of three functional layers:1. The top layer is a mounting foil, has a weak adhesive layer facing the sticker and is designed to transfer it to any smooth surface (tiles, plastic, metal, wood, glass, wallpapers).2. The middle layer is the vinyl sticker itself.3. The bottom layer is a siliconized paper backing, which protects the sticker's adhesive layer from contamination and damage.

Make sure the entire surface , on which you apply the decal, is free from dirt or oil. If using a sponge or wet cloth, dry the surface completely.---- Step 2: Position the decal on the wall. This will ensure the decal is applied to the desired location.---- Step 3: Prepare the decal. With the design facing down, slowly peel off the backing . If the decal sticks to the surface of the backing, stop and roll it up a little and try again.---- Step 4: Apply the decal. Carefully place your design in the desired location with the sticky side of the transfer tape and the design facing the target. You can gently wipe away any imperfections or bubbles with a credit card. (The more design you get to stick, the easier it will be to remove the transfer tape).---- Step 5: Remove the transfer tape. Very slowly remove the transfer tape from the surface. Do not rush. After removing the backing, the sticker should stick to the surface.
