Celebrate your team on game day (and every day). A bartender staple, this two-piece stainless steel Boston shaker is perfect for thoroughly combining ingredients and getting cocktails perfectly cold. Simply measure out spirits and flavorings into the smaller container, add ice cubes and top with the larger container to form a tight seal. Then flip so smaller container is on top and shake like crazy for 10 to 15 seconds. When finished, separate containers and serve. A stamped maximum fill line prevents overfilling.Introducing the NFL Game Day Collection Our bestselling essentials, now made for the team you cheer on every Sunday.
