This ice ball mold can produce 4 oversized transparent ice balls with a diameter of 2.5 in. at a time. Compared with ordinary ice cubes, it melts more slowly, keeping all kinds of beverages like whiskey, cocktails, wine, and brandy cool for a long time without diluting the drinks quickly, ensuring that every sip is mellow and refreshing. The ice balls are crystal clear and have a smooth surface, and they seem almost invisible when placed in a glass, adding a unique visual effect to the beverages. When using it, just fill the mold with water, put it in the freezer for 26-30 hours, and then you can easily take out the formed ice balls. The operation is simple. The mold is made of high-quality silicone, which has excellent durability and a non-stick feature, making it easy to release the ice balls. It is suitable for various occasions such as family gatherings and festival celebrations.
