These are earring parts made of skin-friendly surgical stainless steel. This is the price for 10 pairs. Made from the same material as scalpels and scissors used in surgical operations. The stainless steel used is high-quality SUS316L. Highly recommended 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 professionals incorporate them into their own creations? In my shop, even those who experience allergic reactions to gold and 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.
