Look at your illustrations so that I can help you evaluate the price and appearance.
You can also provide the inspection certificate number, weight, grams (details are also after the decimal point) and the full name of the inspection institution.
This way, I can help you check the certificate and then help you evaluate it after seeing the certificate map.
For mobile phone users, please install Baidu Know Client to explain.
Or you can upload the picture to your Baidu space photo album, and I can check it.
PS, if you take a picture, it is best to take one in the natural light by the window and put it in your hand, so that the color reproduction is more realistic and conducive to judgment.
thank you
