Thank you for viewing! Round ball earrings (10K gold) K10, combined with catches (18K gold) K18. *The catches are slightly different in type and size between pink gold and yellow gold, but both are 18K gold. Please check the photos. *I took a picture of the hallmarks, but the photo quality is limited due to their small size, but the hallmarks are definitely present. This is a combination of simple round ball stud earrings (10K gold) and posts (18K gold). They are understated but unique, and I loved them, but I no longer have the opportunity to wear them, so I'm putting them up for sale. I purchased them about two years ago. There is no particular brand, and I bought them at a jewelry store in Sannomiya, Kobe. I used them for about a month, but I lost the catches, so I will include 18K gold catches. I have stored them with care, but they are stored at home by a private individual. Please purchase only if you understand that they are a home-stored item. No claims or returns are accepted after purchase. Please check the condition in the photos and consider carefully before purchasing. Please refrain from purchasing if you are nervous or seek perfection. *Disinfected☆ Hallmarks: K10 on the catches, and all parts of the earrings are 10K gold. K18 on the posts. Immediate purchase is welcome♡ Thank you very much m(_ _)m
