For most vinyl decals that will be used outdoors like car windows or signs, I only use Oracal 651 vinyl. This is permanent vinyl. If you decide to remove a decal use a hair dryer and a scraper.
The price shown includes free shipping in a rigid photo envelope without tracking.
Photos shown are screenshots of the actual decal.
