Hello, it is impossible to evaluate the price only by your description or the test data of the certificate.

Look at your illustrations so that I can help you evaluate the price and appearance.

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
