For the River Shell Convex Patterns range, Freshwater Shell and Seashell Mother of Pearl is used. The convex forms of the shell or shell chips used, give the tiles a distinct three-dimensional look. The quality of the Mother of Pearl shines through. The shells are combined with a backing of acrylic, magnesium board, mesh, or aluminium honeycomb. Since the shells are 100% natural products, no two are exactly the same. Therefore each product will also be individual. Tile sizes are 300x300x2mm (when the 25x25mm shell chip size are applied) and 305x305x2mm (for any other shell chip size). The tiles are suitable for several indoor usage, such as wall and floor tiles, table tops, basins, baths, showers or decorative products such as vases, photo frames, and boxes. The material is resistant to normal non abrasive bathroom creams; no harsh chemicals should be used.
