This is a Cocktail Shaker is a new and functional design for shaking and serving drinks. When shaking, hold the lid in place to block the pouring spout. To serve, simply rotate the lid a few degrees, and the pouring spout becomes visible on one side of the shaker. An air inlet on the other side of the shaker ensures a nice, even flow when serving. The pouring lip retains any ice cubes without the use of an extra strainer and it doesn’t drip! It’s even dishwasher safe.
