Depending on the temperature environment, the ICE is a product that absorbs heat and dissipates heat while freezing and melting (solid-liquid) repeatedly depending on the temperature environment. Maintains an optimal cooling temperature and prevents skin breakage and frostbites caused by excessive cooling. Quickly regulate your body temperature, and effortlessly cool down your body. Cools faster than water or other refrigerants and lasts longer. If you put it in ice or cold water, it will cool in a short time. No need to worry about the product bursting even if it gets liquid. The cooling effect will last through repeated use. Approximately 30% lower specific gravity than water, making it lighter.
