Ice Pack Water Bottle Type, Ice Bag, No Condensation, No Water Needed, Portable Ice Pack, Heatstroke Prevention Goods

【No Water or Ice Needed! Convenient Portable Water Bottle-Style Ice Pack】 This portable bottle-shaped ice pack features a cooling stick with a built-in cold gel, stored inside a thermos bottle. Unlike traditional ice packs, there's no need to fill it with water or ice each time. Simply freeze and insert the stick for immediate use. It's perfect for commuting, outdoor work, sports, and as a summer heatstroke prevention and cooling item.
【-5°C Freezing Gel for Colder, Longer-Lasting Cooling】 The stick contains a cold gel with a freezing point of approximately -5°C to -10°C. Compared to conventional ice packs that use water or ice, this provides a more intense sub-zero cooling sensation that lasts longer. It's ideal for icing the neck or wrists, cooling down after sports, and staying cool during golf.
【Air Insulation and Absorbent Cover Prevent Condensation】 The insulated structure, with an air layer between the cap and the ice pack, minimizes the impact of external air on the cooling surface, effectively preventing uncomfortable condensation on the cap. Additionally, a dedicated absorbent cover for the cooling stick is included to soak up any internal drips. This thoughtful design prevents your clothes and bag from getting wet.
【Leak-Proof Design for Worry-Free Bag Storage】 The cooling gel stick features a completely sealed structure for peace of mind. Unlike traditional ice packs, there's less worry about loose lids causing leaks, making it easy to carry in your bag. You can safely and stylishly cool down anytime, anywhere, without the hassle of spilling ice water.
【3-Way Use: Cool, Drink, Warm with Tsumutan】 Tsumutan is named from tsumetai (cold) and tumbler or yutanpo (hot water bottle), representing its new ice pack bottle design. In summer, use it as a water bottle-style ice pack. Remove the cooling stick, and it becomes a personal bottle for drinks. In colder seasons, it can even be used for warming care, offering 3-way functionality. Recommended for those looking for an ice pack, water bottle, thermos, or bottle-type ice pack.
