The Blanco 440194 Diamond 33-1/2-Inch-by-22-Inch Single Bowl Kitchen Sink (Anthracite) is made from Silgranit which withstands extreme hot and cold fluctuations and is a uniquely resilient material, less likely to break dinnerware and fine crystal. Softly rounded drain grooves serve as a point of elegance as well as function. Item does not come with the mount clips.
