The project of Ruixiang stainless steel cup originated from Camellia's new thinking on products, users and market during the new crown epidemic period. Under the epidemic situation, consumers pay more and more attention to health, especially the choice of imported products.

Ruixiang uses this kind of material in the main parts of the cup body, which makes the product more comfortable. The stainless steel Camellia cup has entered a trial production stage
