This 5-pack of reusable ice packs is specially designed to keep food and drinks cold. Each pack measures 9.75x9.75x1 inches, filled with a powerful cooling gel mixture that stays colder than regular ice at 18°F (-8°C) and maintains chill for longer. To use, simply fill with water via the funnel, shake, tighten the lid, and freeze to form solid ice-avoiding the mess of melted traditional ice. Made from 100% BPA-free non-toxic materials, the thin yet durable design allows easy cleaning and repeated use, directly replacing regular ice. Perfect for camping, picnics, boating, fishing, and more-just return to the freezer after use for re-freezing. Color: Blue.
