Wrapping it in a towel ensures safe use while preventing burns.

【18 Hours of Super Long-Lasting Cold 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 18 hours when filled with ice water or ice. Even in the scorching heat of midsummer, the ice put in the morning will not melt by evening, providing all-day coolness. Unlike traditional non-woven fabric types, condensation does not form on the surface, so there's no need to worry about your bag or clothes getting wet. It's perfect for staying cool on the train during your commute or at sporting events, and its optimal performance makes it ideal for heatstroke prevention during outdoor activities and commutes.

【Compact Size & Full Features】 The main unit measures approximately 173×53mm with a capacity of 140ml, making it compact and easy to carry without being bulky. It fits easily into small bags during the summer. The material is highly durable, and it comes with an instruction manual for peace of mind, even for first-time users.
