- Three sizes for versatile use: hollow cylindrical ice cubes in three different sizes, stackable as needed, and designed to fit 20-40 oz glasses. Comes with a removable box to prevent odor and dust, helping you keep fresh ice. - Keeps drinks cold longer: The large ice cubes melt slowly, helping maintain the beverage temperature and reducing dilution. - Easy to use: Fill with water, freeze for 8 to 12 hours, then twist to release clear, icy cold ice cubes. - Durable, easy to handle material: Made of thick, sturdy silicone for simple demolding. Includes a sealed removable lid and container to keep the ice cubes stable and free from contamination. - Practical use scenarios: - Home use with large tumblers for water, juice, or cocktails, ensuring long-lasting chill without quick dilution. - Parties or gatherings where you need a steady supply of large, clear ice for multiple glasses (20-40 oz). - Small bars or coffee shops that want batch-made ice to keep drinks cold throughout service with minimal handling.
