[Super Long Cooling for 20 Hours with Double Vacuum Insulation] This cooling item combines thermos-like insulation technology with skin-friendly flexible material. The double structure, featuring high-quality stainless steel on the outside, a soft silicone stick on the inside, and a vacuum insulation layer in between, maintains a cool sensation for up to 20 hours with ice water or ice. Even under the scorching sun of midsummer, the ice put in in the morning won't melt by evening, providing all-day coolness. Unlike traditional non-woven types, condensation is less likely to form on the surface, so you don't have to worry about your bag or clothes getting wet. The ability to feel coolness at hand anytime, whether on your commute or at a sporting event, makes it ideal for preventing heatstroke during outdoor activities and commutes.

[Comfortable Fit with Flexible Silicone for Full Body Contact] The silicone material used for the main body is highly flexible, and its soft, elastic nature naturally conforms to body parts such as the neck and underarms. There's no worry of the cold feeling excessive, and it can be safely used in contact with the skin by everyone from children to the elderly. It provides a comfortable cooling experience in various situations, such as a neck cooler for summer sports events or for cooling your hands in the office. Its simple structure is easy to wash, and it becomes clean immediately by rinsing with water when dirty, which is also attractive. It also considers an eco-friendly design that allows for repeated use.

[All-Season Dual-Use Multi-Function for Both Cooling and Heating] With a heat resistance temperature of up to 100℃, it can also be used as a hand warmer in winter by filling it with hot water. It can be used as a pocket warmer simply by adding hot water. In hot weather, it keeps your neck cool as an ice pack, and it's also useful for cooling muscles during sports or for cooling your head when you have a fever. Its versatility for year-round use greatly improves cost performance and enables sustainable use that is also environmentally friendly. It's a multi-use item that supports your lifestyle and is useful even during seasonal transitions.
