Addtech Large Instant Cold Compress Ice Pack is a one-time use compress that can be easily used. By squeezing the pack, the liquid within the pouch breaks, causing a chemical reaction inside the pouch which produces a cold and harmless chemical.
Remains cold for approximately 15 to 40 minutes and produces temperature as low as -5 degrees Celsius. Does not need refrigeration. The ice pack is small and portable, making it effective to carry around for when cold therapy is required. Generally used for first aid.
