• Silicone ice tray designed to create cylindrical ice cubes of different sizes, perfect for cooling drinks in large containers such as 30-40 oz cups. • Larger ice cubes melt more slowly, helping to keep drinks cold for longer. • Made with food-grade silicone, BPA-free, flexible, elastic, and reusable. • The cylindrical shape allows drinks to dilute less and stay cold for longer. • Compatible with glasses and cups, makes it easy to use straws, and is suitable for coffee, cocktails, whiskey, juices, and other beverages. • The flexible mold allows for easy removal of ice cubes; it is durable, easy to clean, and store. • Removable lids allow you to stack the trays in the freezer, protecting the ice cubes from odors and dust. • Can be washed by hand or in the dishwasher, air dried, and stacked for convenient storage.
