No crystal, no problem. This Crystal Cube Ice Tray will add a sophisticated touch to basic glass wear. Made from silicone, the tray features individually molded compartments with intricate designs, etching ice cubes with a refined, crystal-like pattern. A lid protects cubs while in the freezer, while the food-grade silicone allows for easy removal and is dishwasher safe. Each tray produces four 2.25-inch ice cubes that melt slowly to prevent diluting cocktails and spirits.
