Product Description
The thermos is made of double stainless steel and other materials, and the vacuum in the middle can effectively prevent heat transfer, so as to achieve the function of heat preservation or cold preservation. It can be used to preserve hot water, coffee, tea and other drinks for a long time, so that people can drink the liquid at a suitable temperature when they need it.

This stainless steel thermos has a capacity of 3 liters, a height of 34 cm and a bottom diameter of 15.5 cm. It is often used in homes, offices and other places to store hot water, tea, etc. for a long time and is convenient to use at any time.


The silicone sealing ring is made of food-grade silicone material, which is non-toxic and safe. It features excellent elasticity and resilience. When the lid is securely tightened onto the pot body, the sealing ring undergoes elastic deformation under compression, tightly filling the gap between the lid and pot body. This creates sufficient contact pressure to effectively prevent liquid leakage.

This thermos features a thoughtfully designed handle. The non-slip material ensures stable grip even when hands are wet or in humid environments, allowing secure water pouring. The ergonomic handle shape conforms to the natural hand curve, providing comfortable and long-lasting comfort that enhances the overall user experience.


This thermos features a wide-spout design that delivers multiple benefits. Firstly, it ensures smooth pouring of hot water, coffee, and other beverages without spillage. Secondly, its easy-to-clean design allows hands or cleaning tools to reach every corner, making thorough cleaning effortless and maintaining optimal hygiene inside the container.
