The Laguna Series Tumblers by Cambro have the look and feel of glass, but are made from dependable, break resistant SAN (Styrene Acrylonitrile). The hammered texture on the tumber hides waterspots and scratches. The tumbler has a height of 6-1/16'' with a top diameter of 3-11/16'' and a bottom diameter of 2-3/4''.
