From Bruce Wayne's personal collection, solving the age old dilemma: the cool and refreshing taste of liquor on the rocks, or the full flavor of a neat glass (no ice). Now you can savor the cool and smooth taste of drinking whiskey on the rocks without the normal dilution with an ice ball whiskey glass. Simply fill a 2" ice ball mold with water, freeze, and let the shaped whiskey glass guide the ice ball around the bottom of the glass, chilling and unlocking the aromatics of your drink as it rolls around the glass. Due to the unique shape of the ice ball, the ice melts slower and cools your drink to the perfect temperature, giving you the perfect whiskey on the rocks experience. Includes one ice mold that makes 2” ice balls. Features of Roller Rock Glass:
