Thank you for viewing! I am selling this item because I purchased it on Rakuten around August 2025 but never used it. It is a brand new, unused item that has never been taken out of its bag. If sold separately, I will sell one for 777 yen. The entire lining uses a microfiber towel, so there is no need to worry about condensation, making it perfect for carrying around. It supports both cold and hot beverages and has a maximum cooling function of 9 hours. The material is 3mm thick double-sided aluminum cooling material + microfiber towel. It is sized to neatly store 500ml and 600ml plastic bottles. *When shipping, the item will be folded up compactly from the state shown in the photos.
