This is a stainless steel vacuum flask. In terms of material, the main body of the flask is made of stainless steel, with a surface that exhibits a metallic luster, combining durability and corrosion resistance. It comes with a handle for easy portability and comfortable grip. Functionally, as an insulated container, it relies on the heat-insulating structure of the stainless steel inner liner to effectively block the heat exchange between the inside and outside, maintaining the temperature of the liquid inside the flask for a long time. Whether it's hot coffee in the morning or warm tea in winter, you can always pour out a drink at the right temperature. It is suitable for various scenarios such as the kitchen and office, meeting the daily insulation needs for drinking and enhancing the convenience of life.
