Glass conch tiles are made of crystal glass chips and resin chips with conch. This is the new design to make the tiles lively. The crystal glass chips are high-temperature glass which means the colors will never fade away. The resin chips are randomly added into the tile. And the inner stuff are also random. They may be some conch, starfish and little pebble stone. And the shape can be squared, striped, and round. It makes the tile fantastic. These tiles are terrific for interior design, especially an ocean or beach theme.
