Also great for iced tea, cold brew coffee, soda, lemonade and punch.Create extra-large ball ice for a unique look for your drinks. These unique molds deliver the art and science of slow-melting.Avoid watery drinks by using these large, slow-melting ice balls to chill your drink.

Because the ice puck is relatively large, it needs to be frozen for 6-7 hours. After freezing, pour some cold water first so that it is easier to take out.The sturdy plastic construction, leak proof design, and water fill line make this ice tray easy to use for anyone. The durable, food-grade molds are BPA-free .The set contains two products of the same size and color.
