What is the material of my bottle? I like this kind of cup very much, but I'm worried about its toxicity. Who can elaborate?

Hello! This cup is made of environmentally friendly resin and will not be toxic. Although the cup is resistant to high temperature, it is not recommended to put hot water. Hot water will shorten the life of the cup, so take it with you.

Environmental protection resin is the most widely used and safest in cups at present. Cheap imitations on the market are usually made of PV or PC, which has been used for a long time. Harmful and toxic substances will slowly penetrate, directly affecting health.

If you buy it, you'd better go to a formal designated official website.
