With a diameter of 5.5 centimeters, these ice balls are not just a visual treat but also enhance the cooling capabilities of your beverages. Impress your friends during gatherings or casual hangouts with drinks that are served at the perfect temperature. Scientific studies suggest that this unique shape optimizes the cooling efficiency of the ice, allowing your drinks to chill faster and stay cold longer. You can also freeze fruit juices and other ingredients, which will gradually release their aroma and flavor as they melt in your glass. Made from durable plastic, the molds can be easily opened in the middle for effortless ice removal, and a silicone stopper secures the filling hole.
