Margaritas, Daiquiris, Mai Tais and more. Creating ideally shaken cocktails at home just got a lot simpler. With easy-to-read measurements on the glass and a cap that doubles as a 1.5 oz jigger, this 18 oz glass cocktail shaker is just what you need for your next party. The leak-proof design allows you to shake cocktails with confidence and the silicone boot on the base prevents slips and spills on the countertop. We agree with Mr. Bond, we like our drinks shaken, not stirred.
