This is a neck ring. I think it will be useful in the coming season ^_^ ⭐️ This neck cooler is for the neck and is made of a mysterious ice "PCM material" that freezes in spaces below 28 degrees Celsius, keeping the ring cool even in the hot summer season! It efficiently cools the carotid artery in the neck at a comfortable temperature, so it is also recommended for heatstroke prevention! It doesn't get too cold like ice, so there's no risk of cold injury and it's gentle on the skin ♪ ⭐️ Even if it melts once, it can be frozen again and used repeatedly just by placing it in a cool space with air conditioning! It freezes even faster by putting it in the freezer or soaking it in tap water, so it can be used for sudden outings. ⭐️ The design fits around the neck and is difficult to fall off. It can be used in various situations, such as for those who move actively in sports, those who work outdoors, during commuting to work or school, those who fish, those who do housework, those who are concerned about hot flashes, activities in spaces without air conditioning, after taking a bath, or for a change of pace.
