Nihon Department Store Igusa Tatami Book Cover Anchor

This item has been stored on a bookshelf since it was opened and has been used only a few times to attach to other books before being removed. It is likely that it has never been used in practice.
Therefore, I believe there is almost no sign of use or discoloration, but please only purchase if you understand that it has been stored long-term by an amateur in its original packaging.
