The Boston Shaker is used by top bartenders around the world and is an indispensable tool thanks to its durable construction and versatility. Each Boston Shaker set contains both a top and bottom piece designed to fit together for a tight seal when combined. Unlike shakers that use glass, our Boston Shakers use high-grade metal for both tins to ensure there is no risk of breakage with the change in temperature. This beautiful shaker comes with a stunning copper finish.
