What kind of thermos cup is the safest?

Stainless steel vacuum liner mug is the safest.

First, the thermos bottle works best. In hot weather, we can use insulated bottles of ice water or ice cubes to make you feel cool at any time. Hot water can be poured in winter, so that you can drink hot water at any time.

Second, the stainless steel vacuum liner thermos cup is made of stainless steel inside and outside, refined by advanced vacuum pumping technology, with elegant appearance, seamless liner, good sealing performance and good thermal insulation performance. You can put ice cubes or hot drinks. At the same time, functional innovation and detailed design also make the new thermos cup more connotative and practical.

1. Before use, preheat or precool with a small amount of boiling water (or ice water) 1 min, and the heat preservation and cold preservation effect will be better. After putting hot water or cold water into the bottle, be sure to close the cork to avoid scalding caused by water leakage.

2. Hot tea will change color if it is kept warm for a long time, so it is more appropriate to use tea bags when going out. Please don't put the following drinks: dry ice, carbonated drinks, liquid salt, milk, milk drinks and so on.
