Just pop the Whiskey FREEZE™ in the freezer for 2 hours and the proprietary cooling gel freezes solid inside the double-walled chamber, providing thermal insulation that keeps your drink chilled for hours. It helps subdue the overpowering flavor most common in cask strength whiskey and, unlike melting ice, these cups don't water down your drink!
For frozen concoctions, freeze Whiskey FREEZE™ Cooling Cups for at least two hours to keep your drink between forty-three and fifty-three degrees Fahrenheit.
