Colored glass mirror tile is HAVING A QUALITY ISSUE WITH HOLES IN THE SILVER BACKING AND IS SOLD AS IS. SEE PHOTOS. These places can be cut out if you are using pieces. The silver backing is covered with an epoxy coating to protect it. The glass is actually colored (for the non-metallic colors) instead of being a cheap surface coating. Sold in sheets of 36 tiles face-mounted on clear plastic film. We also have 1-lb bags of cutting scrap from these sheets. Click on a color to see the full product description.
