This ice neck ring is designed to fit snugly around the neck and not fall off. Furthermore, it is lightweight and does not put a burden on the neck. 【High-quality material, refreshing and no condensation】This cool neck ring uses the latest "PCM material". While general substances increase in temperature with the surrounding humidity, PCM stops at a constant temperature even if the surrounding temperature rises, absorbing heat and maintaining a constant temperature. Also, it does not condense, so it does not wet your clothes during use and feels refreshing. The cool neck ring freezes naturally below 28°C and is an item that can be used repeatedly anywhere, indoors or outdoors. 【Easy to use, long-lasting cooling】This cool neck ring can be used simply by putting it around your neck. In addition, the carotid artery is located in the neck, and cooling this area can cool the blood flowing throughout the body, effectively cooling the whole body and preventing heatstroke. Cooling duration: 15-20 minutes in the freezer or refrigerator, about 20 minutes in ice water or cold water! Can be used for 60-120 minutes based on an outside temperature of 25-40°C. Please refrain from purchasing if you are sensitive to items stored at home. Please purchase only if you understand. ⭐️ Instant purchase OK ⭐️ ✨ Thank you ✨
