Squared soap dish in black Marquina marble with little holes for water. Each piece is in a way unique (since each marble block is different in veins and shades) and handcrafted in Italy. Slight variations in shape, color and size are to be considered a guarantee of an handcrafted creation. 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
