Food grade materials: Our ice cube molds are made of high quality food grade material, BPA free, completely healthy. Make perfect round ice balls: Food grade material to maintain the same temperature on top and bottom of the ice maker mold. In the freezer layer (-16), the ice trays can be formed after 7-8 hours of freezing and you can get perfect round ice cube instead of a traditional ice cube shape. Easy to use: The circular ice cube mold consists of a tray and a lid with small holes. Just pour about 400ml of liquid into the tray at a time and close the lip. If you put the mold in the freezer for 6 hours, you can get 33 spheres/balls. Best choice all year round: Whether you're sipping a few cold drinks in your private pool to ward off the hot summer, or sitting next to the fireplace with your dog and enjoying some bourbon to unwind after a busy day at work in the cold winter , this spherical ice mold is the best choice for you to make ice. Multi-functional ice trays: Instantly chills your drink, great for sipping whiskey, scotch, cocktails, and more. You can use the trays to freeze baby food, smoothie cubes, lemonade, coffee and other juices.
