Glass: it has a wide range of uses, and can hold water, drinks, tea and other drinks without peculiar smell. Suitable for people who are used to holding all kinds of drinks in one cup.
Note: it is best to choose high borosilicate material for glass, which has the characteristics of high ground expansion resistance.
Why not recommend stainless steel cups?
Stainless steel cup: the heat preservation and carrying effect is better than glass. The market for stainless steel cups is too chaotic. Non-304 materials are easy to cause heavy metal migration, and their applications are relatively narrow. Even the 304 material can't hold drinks, salt water and other substances. Long-term use of chromium and nickel in human body will cause irreversible and destructive effects on immune system.
Future Water Cup Material-Titanium Cup
Titanium cup: harmless metal with strong corrosion resistance. The same cup is widely used to hold all kinds of drinks, and the titanium cup itself has sterilization function. At present, the mature technology is mastered by a few enterprises in a few countries, which is the future choice of consumers.
