Mixing your own drinks is so much cooler with the Corkcicle Cocktail Shaker. Using their signature triple-insulated stainless steel, your drinks will stay icy but your hands will stay warm as you shake up your own consummate cocktails. The leak-proof lid screws on and doubles as a measuring cup and the built-in strainer makes pouring and serving mess free. Like all Corkcicle Canteens and Tumblers, the Cocktail Shaker has easy grip flat sides and a non-slip bottom.
