These are the margarita glasses that keep margaritas chilled between 32° F and 36° F for 30 minutes. The double-walled glasses have a viscous cooling liquid between both layers that freezes after one hour in a freezer, enabling the glasses to chill a room-temperature libation to 36° F in just 2 1/2 minutes. The glasses are made from durable, hand-blown borosilicate glass, they each hold 9 1/2 ounces, and their shapes impart a celebratory spirit to gatherings. Hand wash. Set of Four. 7 1/2" H x 4 3/4" Diam. (13 oz.)
