ICE BAG plus is a small ice pack product with cold-sensing thermochromic gel and elastic hook and loop tape. The user can put on the elastic hook and loop fastener according to the size of the affected area and then arrange and assemble the ICE BAG plus freely. The use of ICE BAG plus not only improves the existing problems of large-area ice packs but also prevents allergies and frostbite caused by direct contact with the skin of the elderly or infants. The thermochromic microcapsules in ICE BAG plus can also change the color temperature, allowing users to replace them in time.
