Take a shot at throwing a great party with this Quaffer double bubble layered shot glass set. Constructed of thick weighted glass, this set of eight glasses feature a patented design that allows you to have both the shot and chaser in one glass. Simply pour any chaser in first, allowing it to fill the bottom of the hourglass shape, then pour the liquor on top. The liquids will stay separated until consumed, giving you the most unique shot experience you will ever have. Although the Quaffer is called many names, such as a double bubble shot glass, a snorkel shot glass, a jigger chaser shot glass, an over under shot glass, or a jagerbomb glass, this design is by far the most user friendly around. Designed by Jimmy Quaffa, much thought and research was put into making sure that it will provide the best shot experience. This set of shot glasses also come with a recipe card so that you can get the most fun out of your shots, with recipes for whiskey, tequila, and vodka.
