The Sistema Shaker To Go is the perfect solution for making your shakes on the move. When shaken the grooved base helps to agitate powder mix drinks, while the spiral spider not only breaks up the powder it also will aerates the liquid. It has an inserted grip for secure handling and an internal thread so that the base can be comfortable used as a drinking cup.
