I bought this for the summer, but I no longer need it as I won't be working outdoors, so I'm selling it. It's brand new and unused. Basically, everything in the photos is included. New material P.C.M! Unlike ice packs! Maintains 22°C!! This special material changes from liquid to solid when cooled, and can solidify when cooled in temperatures of 22°C or lower, or even in water. In an outside temperature of 25-35°C, it can cool for approximately 2 hours to 1.5 hours (approximately 4 hours to 3.5 hours for the 3.0 version). It can be used repeatedly, making it economical. Class lowest temperature 22°C (Compared to other companies' products sold in 2020, according to our research)
