Take it from England's most famous spy: martinis are meant to be shaken not stirred. With its impressive 28 ounce capacity, this shaker cup can make cocktails to accommodate a crowd. The stainless steel liner will resist rust and corrosion and keep drinks cold until served. When paired with a simple drinking glass, this shaker cup can be turned into a bar shaker in a pinch to turn out margaritas. With the soft rubber coating, not only does it provide a comfortable slip-free grip, it also prevents condensation to build up on surfaces. Pair this shaker with the Hawthorne strainer from the bar collection to strain and serve cocktails with ease.
