Now personalize with a single initial With the Whiskey Wedge, now you can keep your favorite spirits chilled without watering them down. Each unit comes with one Double-Old Fashioned Whiskey Glass and one silicone mold. Simply add water into the double old fashioned glass, insert the mold, then freeze. The ice forms into a wedge and, similar to a glacier, melts slowly due to the reduced amount of surface area. Drink with your favorite liquor, liqueur or cocktail for all the taste advantages of “on the rocks”. It’s the perfect gift for any whiskey, bourbon, scotch, or tequila drinker. Dimensions: 4″ H X 3″ W X 3″ D Approximate Capacity: 1.5 fl oz.
