The sample for this came as 6 stones hot-glued onto a rigid cardboard backing. When I called Wayfair they were unhelpful - just stating that's how it comes. Since there is no option to buy just one sheet, only a carton of eleven square feet, I'll have to decide on this without really knowing if it will work for my shower pan. It works for getting an idea of the color, but useless for knowing how the stones lay on the mesh back and if they'll work with the grade on the floor, or for what the grout lines will look like. Disappointed with both the sample I got, and the customer service.
