Create an attractive backsplash in the kitchen or bathroom with these Metro adhesive wall tiles from Smart Tiles®. They're made of thin, lightweight resin, fitting securely on smooth surfaces. Because these are self-adhesive mosaic tiles, they're easy to install without the need for adhesives like glue or grout. Simply peel off the backing and stick the self-adhesive mosaic tiles to the wall. The material stands up to moderately hot and humid conditions, and removing the tiles won't leave marks behind on walls. This box of four tiles covers 2.2 sq.ft.
