Introducing the Ice Ring Cooler - a revolutionary body cooling solution designed to quickly and effectively reduce body heat. Our product boasts a fast freezing time of approximately 10 minutes in ice water and 20 minutes in a freezer, and can be frozen in various other ways such as in cold water, an ice box, purifier water, or with a car air conditioner. Our cooling technology ensures optimal temperature control, preventing skin necrosis and discomfort. The special refrigerant used in our product has been developed using advanced NASA R&D techniques, originally designed to protect astronauts from sudden temperature changes. It freezes faster than water or other liquids, maintaining a lower temperature for longer periods of time. When melted, our refrigerant does not form water droplets on the surface, ensuring a mess-free and hassle-free cooling experience. Our product provides approximately 45 minutes of cooling relief and has been tested to have a temperature difference of approximately 1.2°C before and after use (although this may vary depending on environmental factors). Our eco-friendly TPU material and high-frequency bonding technology make our product durable and semi-permanent, ensuring a long-lasting and reliable solution to beat the heat!
