Brand new, unused! Color: Khaki 【Stress-Free Drinking Experience】 Designed for a natural drinking experience like a glass or mug, it eliminates protrusions like screws for a smooth mouthfeel and allows you to drink from any 360-degree angle. The structure catches ice and prevents drinks from gushing out, ensuring a comfortable finish to the last drop. 【Excellent Heat and Cold Retention】 The bottle body has a double-layered stainless steel construction. By creating a vacuum between the outer and inner layers, heat loss through convection is prevented, providing high 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 at a delicious temperature anytime. 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, which won't interrupt your work.
