There are a lot of hot cups on the market. Many people are worried about buying unqualified hot cups. In fact, if they want to buy qualified hot cups, it is better to buy them in a regular shopping mall. When they purchase, they will not choose non qualified brands without formalities. They can filter some unqualified hot cups.

Secondly, when purchasing, you must see whether 304 or 316 materials are marked. If the 304 or 316 material is marked but still rusts during use, you should consider buying counterfeit products and should not continue to use them.

In addition, stainless steel will be printed with "18-0" and "18-8". The front number represents the chromium content, and the back number represents the nickel content. "18-8" is 304 stainless steel.

If the inside of the insulation cup is uneven and rusty, it is better not to continue using it to avoid heavy metal poisoning.
