Thank you for viewing! ☆(=^ェ^=)☆ ❤️ Price negotiation → Highly welcome ⭐️ First come, first served ⭐️ Initial defect warranty included Keeps your neck cool even in the hot summer! A neck cooler for the neck made with "PCM material," a mysterious ice that freezes in spaces below 28 degrees Celsius. It doesn't get too cold like ice, so there's no risk of cold injury and it's gentle on the skin♪ Even if it melts once, you can freeze it again and reuse it just by placing it in a cool space with air conditioning! It freezes even faster by putting it in the freezer or soaking it in tap water, so it's ready for sudden outings. 【Melting Point】28℃ 【Material】TPU, PCM (Phase Change Material) 【Features】 【1】Freezes naturally below 28℃! A neck ring for the neck that wraps a water-soluble gel "PCM" that freezes below 28℃ in durable TPU material. 【2】Doesn't condense, so it's comfortable. Unlike ice, it doesn't condense, so your neck stays dry and comfortable at all times. 【3】Moderate cooling lasts. Maintains 28℃, prevents excessive cooling, absorbs body heat, and provides a comfortable cool-down. 【4】Can be reused many times. It becomes liquid above 28℃ and freezes below 28℃, so it can be reused by cooling it. 【5】No power or batteries required. No power or batteries are required, making it an economical and eco-friendly heatstroke prevention product. This product freezes naturally. When you use the PCM material inside in a solid state, you will feel a comfortable coolness of about 28℃. If the contents become liquid, cool it in an environment of about 28℃ or less, such as a refrigerator, a place where air conditioning blows, or cold water, and solidify it. The lower the temperature, the faster it solidifies. 【Caution】 Product images are 5.6. The color of the product may differ slightly from the photos due to differences in lighting and screen settings.
