Wish your drink would stay chilled longer? Our mega-block tray creates six large sized cubes, which melt slower than normal sized cubes. Made of food-grade silicone, the tray's convenient, flexible construction provides easy release of ice cubes, is leak free and won't crack like plastic trays! For less spills, the tray will stay firm when filling and easily nests to double stack in the freezer. An easy solution to all your ice-related problems.
