No certificate is not necessarily fake. When we got the goods in Nanyang or Guangzhou, we basically didn't have a certificate. We always pay the money first, then settle the account, and then make our own certificates. Generally, a certificate costs tens or even tens of dollars, mainly to reassure ordinary consumers. The most important thing is to see if there is any problem with the material of the jade bracelet itself, whether it is fake or not. I hope to use pure mobile games.
