Must Have! ?Necessity is the mother of invention.? For vodkaphiles, it is a necessity to have freezer-cold shots of vodka ready for those moments when nothing else will do. As a result, the CoolShot was born, US Patent No. 6,446,460, a unique crystal glass with a precision fitting top that enables shots of vodka (or other liquors) to be stored in a freezer for extended periods of time, ready for consumption. The CoolShot is the only product for storage and consumption of vodka at subzero temperatures. NAR Inc. 401-849-4480
