Generally speaking, the life of the thermos cup is only about three years, after which it will not keep warm.

When using, do not hit and deform, and when the cap is tightened, do not violently twist it, and clean it with a neutral detergent after use.

The most fearful thing about the thermos cup is bumping. Although it is made of metal, it is easy to buckle and deform to produce dents. The deformation will affect the vacuum degree of the interlayer, and the insulation effect will be worse. Therefore, it is necessary to avoid collisions as much as possible.
