I bought these tiles to cover the old tile backsplash in my mother's kitchen. These tiles are SO easy to work with, can be placed right on top of old, existing tiles, and look just like real glass tiles! When you step back about 3 feet from the tiles, you really cannot tell that they are not real glass tiles. The luster of these tiles is gorgeous! My mother and I love these tiles and they completely improved the entire look of her kitchen--for a small sum of money compared to ripping out the old tiles and replacing with real ones! Thank you to Great Offer Stock and the company who makes them!
