The Random Belgium Slate is a single stamp. Love the look of natural random stones with the rugged texture of slate? Proline's Random Belgium Slate gives you stones ranging in size from approx.8″ x 10″ to 12″ by 18″. Each stone has a lightly hammered edge and defined grout lines for a natural quality. A single tool application and, as wth all Proline's patterns, we offer this pattern in a thin-flex mat for finishing against walls and walkway edges. Belgium Slate adorns the background of these stately stones.
