Cutting Board is made of marble in brown shades. The tray is rustic and has a handle with a string which makes it ideal for hanging. The beauty of a natural stone is that no two pieces are exactly alike. Each one is a unique work of art forged by Mother Nature over millennia using heat, pressure and lots of different minerals and organic materials. The way these minerals settle into the stone is what causes the huge variety of colors, patterns, textures and veins in each slab.Do not use in the oven, microwave or dishwasher.
