Viski Clear Ice Cube Maker for Whiskey CocktailsA single large clear cube is the detail that makes a home Old Fashioned look and taste like the bar version. This clear ice maker from Viski gives you two roughly two inch crystal clear cubes that melt slowly, chilling a neat rye or a stirred drink without rushing the dilution. Built from BPA free silicone and stainless steel, it measures 6. 5 x 4. 25 x 6. 5 inches and is easy to use at home. Hand wash recommended to keep it in good shape.
