Approximately 23cm to 26cm. I enjoy collecting items, and I purchased this but never used it, so I'm listing it as "like new" due to home storage. It can be wrapped around the arm as a bracelet♪. ※ This item has been stored at home in a dark place for a long time. Please note that this is a personal inspection, and there may be oversights. Price reduced. It will be sent via Yu-Packet Post or Yu-Packet Post Mini. Packing and shipping materials will generally be reused. Please understand this before purchasing.
