The Original, do-it-yourself peel and stick Smart Tiles are made of an adhesive substrate topped with a gel component called Gel-O™, giving a 3-dimensional effect. The tiles are lightweight, easy to handle, cut and maintain, and will remain on your walls for as long as you wish them to. The tiles can be installed in minutes over a clean and sleek surface without any mess or specialized tools. Especially designed for kitchen and bathroom environments (i.e.: backsplashes), the tiles are resistant to the heat of stovetops and the humidity of bathrooms (do not use in shower).
