In environments below 28℃, the PCM naturally crystallizes, reducing the perceived body temperature by 5℃ after wearing. It is suitable for various situations such as sports, outdoor activities, and offices. Easy to wear, wrap it around your neck, fit it, and adjust to a comfortable position. [Crystallization Time] Approximately 1 hour in the refrigerator (2-6℃) and approximately 30 minutes in the freezer (-18℃). After removing from the refrigerator, wipe off any excess moisture from the surface before use. If a refrigerator is not available, try cooling it with running water. If placed horizontally, dents may form on the surface after freezing, but this is a normal phenomenon of PCM crystallization and will gradually return to normal after use. [Cooling Duration] After removing from the refrigerator, it provides a cool sensation of around 10℃ for about 10-30 minutes, followed by a cool sensation of 20-28℃ until the PCM inner core becomes completely liquid. If the cooling sensation feels weak, you can enhance it by gently kneading the product to evenly distribute the PCM inner core. The effect can last up to 5 hours depending on the usage environment. #noeno's seasonal items [Cool Neck Ring, 2 pieces, PCM Material, Neck Cooling, Heatstroke Prevention, Heat Relief Goods, Blue, White, Multicolor, Outdoor, Cool Ring, Ice Ring, Neck Cooler, Unisex, Outdoors, Camping, Air Conditioning Savings, Power Saving, Frosty Ring, Easy Heat Relief, Women, Men, Unisex, Pets, On-site Work, Overseas Travel, Travel, Tropical, Sports Viewing, Commuting, School Commuting, Cooking, Emergencies, Fever, 2 pieces] 482*750.638
