Never worry about a ruined cocktail caused by melting ice again. The Rox & Roll Stainless steel ball will cool your fine drinks... without diluting - while playfully rolling in your drink and never melting down! By rolling the ball around the thumb-hole you will feel the aroma of the whiskey in the air, intensifying the taste while enjoying the rolling motion. When done, simply deposit the balls into their ice molds for easy access and freezing until their next use.
