Our shop is handmade decorative jewelry, which is difficult to reach the quality of precious metal jewelry, and there will be some glue overflow or hand marks. Perfectionists/magnifiers buyers should be careful to take silver needles, which are easy to oxidize and blacken. Ear needles are easy to bend during transportation, and can be straightened slightly. It is not a quality problem. The oxidation process of jewelry is related to the degree of care at ordinary times. Skin care products, sweat, perfume contact, etc. will accelerate oxidation
