These Georgia Tech peel and stick appliqués can be placed safely onto any surface and are sold in a pack with 22 large designs.
Great on painted walls (they never leave any sticky residue) for bedrooms, dorm rooms, and offices. You can move them around at will (they are repositionable over and over) - and you can even replace them on their original liner for later use. Also works on cars. They even go through the car wash- no problem.
So much more versatile than a conventional sticker.
