The ReJigger simplifies the process of making a cocktail by combining all the bar tools you need into one simple tool. No more worrying about measurements - just pour your ingredients into the ReJigger's compartments. Empty the ReJigger into a pint glass filled with ice, place the ReJigger on top to seal, and shake. Once the drink is properly mixed and chilled, tilt the ReJigger to the side and strain your cocktail into a glass. Because it's so easy to use, the ReJigger is perfect for making a quick cocktail after work or for throwing a party where your guests can make their own cocktails.
