Transparent Vinyl Decal has 3-part layers. The bottom layer is the backing paper, the middle layer is the vinyl decal, and the top layer is the transparent transfer paper.
To apply, you simply peel the transfer paper off of the backing paper. Next, place the transfer paper on the surface that you’ve previously prepped, use a hard card or credit card to rub it down, and make sure the vinyl has properly adhered. After that, peel the transfer paper off, leaving the vinyl behind.
