Just pop the Tumbler FREEZE™ in the freezer for 2 hours, pour your favorite beverage and enjoy! The proprietary cooling gel freezes solid inside the double-walled chamber, providing thermal insulation that keeps your drink cold for longer.
For a frosty beverage, freeze Tumbler FREEZE™ Cooling Cups for at least two hours to keep your drink between forty-three and fifty-three degrees Fahrenheit.
