Cool and Refreshing on a Humid Day!】 You need coolness to combat the long-lasting heat! By wearing our neck cooler, you can easily experience a comfortable coolness with a 26°C cooling sensation, allowing you to stay comfortable anytime. 【Eco-Friendly Design, No Charging Required】 This cool neck ring uses the cutting-edge "PCM material." While general substances increase in temperature along with the surrounding humidity, PCM maintains a constant temperature even when the surrounding temperature rises, absorbing heat and maintaining a stable temperature. Freezing starts anywhere below 26°C. You can quickly regulate your body temperature and cool down without strain. 【Neck-Hanging Style for Full Body Cool Down】 The neck has a major artery, and cooling this area can cool the blood flowing throughout the body, effectively cooling the entire body and preventing heatstroke. Cooling Time: 15-20 minutes in the freezer or refrigerator, about 20 minutes in ice water or cold water! If the temperature is very high, the cooling time needs to be longer.
