This tile has the beautiful name "Rose Queen". It is made of crystal clear glass and stainless steel. It is an interlocking design. The little squared chips are designed with an inner crackle effect. It is not a damaged issue. After going through a high-temperature kiln, the mosaics' colors will never fade away. On the back of the tile, it is mesh mounted, and the finish is glossy, so it’s easy for cutting and clean. Please use non-sanded grout for installation.
