1. PROFESSIONAL BARTENDER'S CHOICE: Tough enough for high volume bars and home bars alike, this boston shaker has been hand-selected and tested by professional bartenders to be the highest quality and best shaker available. 2.DURABLE: Professional food-grade Stainless Steel and dishwasher safe for home or commercial dishwashers. This all-stainless shaker set will not break like glass shakers, and has no rubber seal to crack and warp with age. 3.NO DRIPS OR MESSES: Don't take your chances buying shaker tins separately, this set has been selected and tested to offer the perfect water-tight seal. 4.VERSATILE: Use the shaker for shaken drinks like Margaritas, Daiquiris and Mojitos, or use the bottom tin for stirred drinks like the Martini, Manhattan or Old Fashioned. The tins also nest-inside each other for low-profile storage when not in use. 5.Unlike cobbler shakers, this boston shaker set will not freeze shut, drip or spill as you pour out your drink.
