Mirror Tiles are sold mounted on soft, flexible mesh sheets of 25 tiles. We also sell scraps of cutting strips sold in 1-pound bundles. The faces of the tile are flat, but the bottoms are embossed with the patterns depicted in the photos below plus a special coating to prevent glues and cements from oxidizing the silver mirror backing, which is usually a significant problem when using mirror in mosaic art. Our mirror tiles are nominally 3/16-inch, which is slightly thicker than our regular glass mosaic tile. The tiles are nominally 1 inch x 1 inch.
