GAUDEA aluminum self-adhesive mosaic tiles are used for wall decoration, such as kitchen backsplash or bathroom wall tile. Each tile has a brushed aluminum matte finish and a self-adhesive sticker on the back, no grout. Just peel and stick, stick the tile directly to the wall and save time and money on labor. Easy to install! The surface of the tile is heat and moisture resistant, so you can put it behind the stove, bathroom mirror and even on the cabinet.
