Shake your Margarita in a regular cocktail shaker with the original IceBreaker Pro inserted into it to shave the ice. The innovative design creates tiny ice particles and a cooler beverage as a result of its micro-blending surface. In fact, according to our research, a drink shaken with the IceBreaker Pro can be 2 to 3 degrees cooler than a cocktail shaken without it. It can even aid in the breaking up of fruits and berries, as well as the zesting of fruit rinds, elevating mixology to new heights.
