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, wallpaper).2. The middle layer is the vinyl sticker itself.3. The bottom layer is a little thick transparent film, which protects the sticker's adhesive layer from contamination and damage. If you need custom size, you can write to us by mail. Application instructions:---- Step 1: Clean surface. 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 car. This will ensure the decal can be 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.
