Thank you for viewing. I purchased this a while ago at a jewelry store. I loved the design and wore it to my friends' weddings and other events. I'm selling it to organize my belongings. ◯ Size (measured flat) Chain: Approximately 21cm Top: Approximately 2cm (No markings) It will be shipped without a case via Yu-Packet Post Mini. For those who like it♪ How about it? ^^
