Time to replace your boring, old-school ice trays with something more fun like this Ice Ball Maker Mold. This prepares round ice ball spheres which are larger in size and will definitely be a conversation starter among your guests. The tray has been made out of 100% BPA free food grade silicone and is flexible for use and easier to clean. Since the ice ball spheres are large in size, they will melt slowly thus keeping your drinks and beverages chilled for hours. Be it whiskey or a simple glass of lemonade, these spheres will be perfect to beat the heat during summers.
