ICE BALL IS THE PASSING TIME, NOT ONLY THE WAY OF DRINKING. The famous Japanese bartender Takayuki Suzuki said, "In nature, the rocks on the riverbed will become rounded by the perennial erosion of the running water. The ice ball in the cup is not only to lower the temperature of the whiskey and dilute the alcohol, it also represents the passing time." In Japan's bar, the bartender repeatedly taps the ice frozen for at least one week with ice cones until every side is round, which is extremely time-consuming. WITH OUR ICE BALL MAKER, MAKING ICE BALL IS EASIER. 1. Easy to fill. Use a funnel to pour water into the four holes in the lid, or fill the bottom part of the ice tray up with water, then close the lid to squeeze out the excess water. 2. Easy to make a round ball. Leak-proof slot design prevents the water from connecting together so that the ice balls won't stick together, and the ice ball will be more round. 3. Use stably and efficiently. Unique exterior design and thicker silicone enable the ice cube mold to be stably placed, not easy to be deformed. Multiple ice cube molds can be stacked in multiple layers to produce multiple ice balls at the same time. 4. Easy to release. Due to the flexible and non-stick surface silicone, the ice balls are easy to release. 5. Safe to use. Our ice ball mold is food-grade, BPA-free, with no toxins or harmful ingredients. Due to its good chemical stability and temperature tolerance, it is suitable for dishwashers, microwave ovens, and refrigerators.  OUR COMMITMENT We are a responsible seller and believe in the good quality of our products, if you have any questions about our products, please feel free to contact us, and we will provide 100% satisfactory solutions.
