These are essential "basic findings" for connecting parts in handmade jewelry making. ・Round rings Purchased from Kiwa Seisakusho, Oui Oui, etc. Some have been used, and the remaining items are unused but have been opened once, so the bags may have some dirt. I am selling them because I couldn't use them all. They have been stored with care. Thank you for your understanding regarding home storage. Thank you for looking.
