【Eco-Friendly and Safe Materials!】 Utilizing plant-based PCM (Phase Change Material) and harmless TPU (Thermoplastic Polyurethane), we've adopted sustainable materials that consider the Earth and the future. It's safe for contact with the human body, allowing you to use it with peace of mind. 【New Evolution in 2024】 After thousands of repeated tests and improvements, we've selected 24°C German-made PCM and eco-friendly TPU materials, tailored to the comfortable temperature of the human body. To further enhance the cooling effect, we've increased the PCM usage by 70% and extended the cooling duration by 2.5 times. Furthermore, for your peace of mind, the outer fabric uses high-quality, thickened TPU material, which is durable and eliminates concerns about leaks or damage. We collaborate with ISO9001 certified factories for quality control, utilizing cutting-edge manufacturing technology. This ensures the quality of our products. 【For Heatstroke Prevention】 Keeps you cool even in the hot summer season, recommended for heatstroke and extreme heat対策! Even after melting, it naturally freezes again just by placing it in a cool space below 24°C, allowing for repeated use. Also, it freezes more quickly when placed in the freezer, making it suitable for sudden outings. A 28°C cool neck ring cannot provide sufficient cooling effect on a scorching day. This 24°C product offers the best cooling experience. 【Re-inspected in Japan】 We conduct re-inspections in Japan to achieve thorough quality control. We deliver the product in excellent condition with a sophisticated design and a durable reinforced PP package. It's also perfect as a gift. 【Versatile in Various Scenes】 Comfortable for use in various situations, such as for those who play sports, work outdoors, commute to work or school, fishing, housework, those concerned about hot flashes, activities in spaces without air conditioning, after bathing, or for a change of pace. The design fits snugly around the neck and is unlikely to fall off, making it ideal for those who move actively. #CoolRing #NeckRing #ForKids Opened for photography, but it's brand new and unused.
