For a perfect cocktail, it's important to chill the spirits without diluting their distinctive flavors and aromas. A professional bartender's trick is to use these handy silicone molds, which create extra-large cubes of ice that melt slowly and evenly. Set includes two molds-each makes one giant 2 1/2" ice cube. Flexible silicone molds release cubes instantly. Hexagonal design keeps molds upright in the freezer. Leakproof silicone caps create a tight seal. Stackable molds conserve freezer space. Dishwasher safe. BPA-free.
