Good quality. When you install, remember to remove the plastic coatings on the white seashell tiles as it will be much more difficult to clean after grouting. Works well on a countertop because of the thickness and the dimension (doesn't look dated as a tiled counterop at all if you use with a Bostik/Mapei urethane grout- don't use the traditional cheaper powdered grout)..
