Thank you for viewing. This is a bijumam ring (adjustable). Size: Approximately size 11.5 (Japan size) Used a few times after purchase. It has a vintage look to it, so there are some darkened areas. We would appreciate it if the buyer could polish it themselves. Please refrain from purchasing if you are sensitive to used items due to personal storage. Original price was about 4000 yen.
