[Product Details]
PCM (Phase Change Material), a new cooling material developed by NASA.
At a set high temperature, PCM absorbs and retains heat, creating a cooling effect. At a set low temperature, PCM releases stored heat, creating a warming effect. This product is a reusable ice pack that freezes at 28°C and melts at 28°C, allowing for semi-permanent use.
Cooling lasts for approximately 90 minutes.
Maintains coolness for 90 minutes. Even if it melts due to rising temperatures, it will refreeze if placed in a cool place.
Eco-friendly as it doesn't require freezing equipment.
Even if it melts, it refreezes below 28°C, so simply place it in an air-conditioned room. If you're in a hurry, it will freeze in about 20-30 minutes in cold water or ice water, or about 20 minutes in a freezer.
No condensation, so your clothes won't get wet.
Unlike ice, which melts and makes your clothes and neck wet, this product has no condensation and its surface remains dry. It won't wet your bag, making it convenient to carry.
Effectively cools the neck.
Just wear it around your neck for a cool feeling! It efficiently cools the carotid arteries in your neck. It's perfect for commuting, outdoor activities (leisure, camping, fishing, festivals), housework, picking up children from daycare, for infants in strollers, for those concerned about hot flashes, visiting nurses, and in places with weak air conditioning. The uses are diverse.
