Extra Large Individual Ice Balls 
With its jumbo 2.5 Inch Diameter size, the ice ball melts slower than ice cubes. It will keep your drink cool longer and melts slower to avoid diluting your drink. You can freeze any type of liquid. Freeze water, juice, wine, alcohol, soup, and baby food. The options are limitless. By having 4 separate mold instead of an ice cube tray, gives you the convenience of being able to find room in any freezer, and with its flat base, it will always stay balanced whilst freezing, without the worry of spilling.
