Efficient Cooling: Delivers lasting freshness with rapid temperature reduction and sustained cooling power. This is enabled by heatresistant technology and a robust ice crystal core optimized for consistent performance. Advanced Chilling Effect: A sealed ice crystal core provides uniform cold distribution and an instant temperature drop, engineered for efficiency cooling and synergistic performance with fanassisted refrigeration. Effortless Cooling Activation: The ice pack activates cooling properties automatically once removed from the freezer, offering a userfriendly solution. Advanced Sealing Technology: Ensures repeated freezing stability and resists compression deformation for safe, longterm durability, with a reinforced, wearresistant outer structure for consistent performance over time. Size, Compatibility, and Material: Designed to fit standard lunch boxes and portable coolers; exact dimensions vary by version. Construction features a sealed ice crystal core and a reinforced, wearresistant outer structure for durability and repeated use. Performance Highlights: Rapid cooling, uniform cold distribution, and durable, longterm usability across multiple freezes. Use scenarios: Daily meals and snacks: Fits typical lunch boxes and portable coolers to keep perishable items fresh at school or work. Travel, picnics, and outdoor activities: Keeps beverages and foods cold during road trips, outings, or camping. Temperaturesensitive items during errands: Helps maintain cooler conditions for cosmetics or small items that require stable temperatures during short trips.
