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.
