1. The hole clip must be purchased in the whole box, otherwise it will be easily damaged during transportation.

2. Don’t choose the flat packaging method for the plate clip, but choose the side to side, which is not easy to scratch.

4. Gold, rose gold and other colors will darken for a long time, which is an oxidation phenomenon, not a quality problem.
