Brand new, unused! Color: Khaki 【Stress-Free Drinking Experience】 Designed for a natural drinking experience like a glass or mug, this bottle eliminates protrusions like screws, providing a smooth mouthfeel and allowing you to drink from any angle. The structure is designed to catch ice and prevent drinks from gushing out, ensuring a comfortable drinking experience until the last drop. 【Excellent Heat and Cold Retention】 The bottle body features a double-walled stainless steel construction. The vacuum between the outer and inner walls prevents heat loss through convection, providing excellent heat and cold retention. It maintains a temperature of 65°C or higher for heat and 8°C or lower for cold for 6 hours, allowing you to refresh yourself with a delicious drink at any time. Furthermore, the design prevents dust from entering even when the lid is removed, eliminating the need to open and close the lid every time you drink, and preventing interruptions to your work.
