WallFlys are removable, repositionable graphics for your wall. Unlike similar products, Wallflys are printed on Photo Tex, not vinyl. Photo Tex is an adhesive back fabric that sticks easily to any flat, non-porous surface and will not leave any residue when removed. It applies without wrinkles and does not rip. Your WallFly will not remove paint from a primed wall and is safe to apply over wallpaper.
