It is very easy to apply on any plain surface. The Decal you received has three parts: Vinyl Decal, Paper Backing, & Clear Transfer Tape. Clean the surface where the decal will be installed. Slowly removed the paper backing making sure that your decal remains stuck to the transfer tape. If part of your decal lifts up with the backing, press the paper backing back down against it until it stays stuck to the transfer tape. Once it's peeled away from the backing, line up & position your decal against the surface to which it will be applied. Use a credit card as a squeegee, to smooth down your decal, making sure that it is completely stuck to the surface. Slowly & carefully remove the transfer tape from your decal, making sure that your decal is stuck to the surface. If you see part of the decal does not release from the transfer tape, press it back down to the surface and repeat the process.
