Grey bardiglio marble utensil holder, made in Italy, Carrara. Each piece is in a way unique (every marble block is different in veins and shades) and handmade by Italian artisans specialized over generations in processing marble. Slight variations in shape, color and size are to be considered a guarantee of a handmade creation. Important: Do not use lemon or vinegar on it, clean only with water and natural soap (like Marseilles soap), do not put in dishwasher. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
