New, Unused Opened for inspection. *Box is torn. This "stainless steel bottle" is perfect for outdoor activities like camping, mountain climbing, and travel, as well as for daily use like commuting to work or school as your "personal bottle." Thanks to its double-walled insulation, it excels at keeping drinks hot or cold, maintaining the optimal temperature for a long time. Even when you put hot water in it, the heat doesn't easily transfer to the outside, so you don't have to worry about burns. It also resists condensation when filled with cold drinks, preventing your hands, bag, or important documents on your desk from getting wet. The wide mouth makes it easy to enjoy the aroma of hot coffee or herbal tea, enhancing your break time. Size: Approx.)
