This item is brand new and unused. I opened it for the purpose of taking photos. I have been using the same item, and this one was kept in storage after purchase. For heatstroke prevention. The ice opening is large, so large ice cubes can also be inserted! Heatstroke対策 with a hands-free, wrap-around ice pack An ice pack that you simply put ice in and wrap around your neck. The double structure of the PU material inner bag and the cover prevents sweat from sticking. It is also comfortable to use as it is less likely to condense and drip. Even just the cover can be wetted and shaken for a cooling effect. Great for sports観戦, camping, golf, gardening, and icing.
