【Ultra-Long Cooling for 20 Hours with Double Vacuum Insulation】
This cooling item combines thermos-like insulation technology with skin-friendly flexible material. The double-layered 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 when filled with ice water or ice. Even under the scorching sun of midsummer, the ice put in the morning will not melt by evening, providing all-day coolness. Unlike conventional non-woven fabric types, condensation does not easily form on the surface, so there's no worry about bags or clothes getting wet.

【Comfortable Fit with Flexible Silicone for Full Body Use】
The silicone material used in 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 concern of the cold feeling being 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.

【All-Season Dual-Use Multi-Function for Both Cooling and Heating】
With a heat resistance of up to 100℃, it can also be used as a hand warmer by filling it with hot water in winter. Simply fill it with hot water and use it as a pocket warmer. In hot weather, it acts as a cooling pack to keep your neck cool, and it's also useful for cooling muscles during sports or for cooling your head when you have a fever. Its year-round versatility greatly improves cost performance and enables sustainable use that is also environmentally friendly.

【Lightweight Design for Excellent Portability for Cool-Down Anytime】
This product features a thoroughly lightweight design, allowing it to be neatly stored in gaps in bags or pockets, minimizing the burden of carrying it. Its convenience is particularly evident in outdoor settings. It can be easily carried not only for leisure activities like travel, camping, and festivals, but also for everyday shopping, commuting, and school.
