Good Grips tools are always just a little more functional, comfortable and easy to use than any others, and their stainless-steel cocktail shaker is no exception. This 16-oz. shaker features double-wall construction that eliminates condensation on the outside, keeping counters and tables dry. It also insulates drinks to keep them chilled longer. A strainer is built in and the cap doubles as a jigger with measurment markings for making drinks. Dishwasher safe.
