These are surgical stainless steel earring parts that are gentle on the skin. This price is for 10 pairs. They are made of the same material as scalpels and scissors used in surgical operations. The stainless steel used is high-quality SUS316L. We highly recommend these for those who suffer from metal allergies. They are reputed to not cause itching even in the summer. You can confidently recommend them to others, so why not use them in your own creations, professionals? In my shop, even those who experience allergic reactions to gold or titanium are using them. They are easy-to-use, simple shapes. Length: 18mm Wire thickness: 0.7mm We also have separate listings for 20 pairs and 50 pairs. No comments needed, immediate purchase is OK.
