It maintains a cool feeling for 20 hours with ice water or ice inside, thanks to a double structure with high-quality stainless steel on the outside, soft silicone sticks on the inside, and a vacuum insulation layer in between. Even in the scorching heat of summer, ice put in in the morning won't melt until the evening, providing coolness all day long. Unlike conventional non-woven fabric types, condensation is less likely to form on the surface, so you don't have to worry about your bag or clothes getting wet. Whether on the train during your commute or watching sports, you can always feel cool at hand, making it the perfect solution for heatstroke prevention during outdoor activities and commutes. 【Comfortable to use, fitting the whole body with flexible silicone】 The silicone material used for the main body is flexible, and the soft, elastic material naturally fits parts of the body such as the neck and underarms. You don't have to worry about feeling too cold, and it can be used safely on the skin by children and the elderly. It provides a comfortable cooling experience in various situations, such as a neck cooler during summer sports events and for cooling your hands in the office. The easy-to-wash, simple structure is also attractive, as it can be cleaned immediately by rinsing with water when dirty, and it is designed to be eco-friendly for repeated use. 【Multi-functional for both cooling and heating that transcends seasons】 With a heat resistance of up to 100°C, it can also be used as a hand warmer in winter by putting in hot water. It can be used as a pocket hand warmer just by putting in hot water. In the hot season, it can be used as a cold pack to cool the neck, and it is also useful for cooling muscles during sports and cooling the head during fever. 【Lightweight design with excellent portability for cooling down anytime】 This product adopts a thorough lightweight design, and can be stored neatly in the gaps of bags and pockets, minimizing the burden of carrying.
