For novice bartenders or seasoned mixologists, the OXO stainless steel cocktail shaker makes whipping up a favorite cocktail a whole lot easier. Just add spirits, mixers and ice, screw on the LiquiSeal top and shake vigorously. With the simple press of a button, cocktails can be neatly strained and poured out of anywhere on the 360-degree opening. The double-wall construction keeps liquid cold.
