This tile has a beautiful name “Rose Queen”. It is made of crystal clear glass and stainless steel. It is interlocking design. After going through high temperature kiln, the mosaics colors will never fade away. On the back of the tile it is mesh mounted, the finish is glossy, so it’s easy for cutting and cleaning. Please use non-sanded grout for installation. Each of the tile is in 12”x12”. We have two options for customers. One option is 10 sheets per box( covering 10 sq.feet). Another is 5 sheets per box ( covering 5 sq. feet). We do offer samples. And we suggest customers to order a sample before full size orders. We have our warehouses both in California and Kentucky. We use UPS ground service to ship tiles which takes 2-6 business days for delivery.
