A Kodansha magazine supplement? It's a Barbapapa multi-case. It might be a mother and child health handbook case. I had it at home, and I was using it for accounting for a while. It's convenient for carrying around things like bankbooks and cards all together. I haven't used it for years since I bought a bankbook case because the number of my bankbooks increased, so I'm putting it up for sale. There are no noticeable large scratches or stains, but there was a faint rust color around the metal fittings. I also put coins in the zippered pouch, so it looks a little blackish. In addition, since it's been stored at home and I'm not a professional, I may have overlooked something. I hope you can refer to the images. If you are concerned, please refrain from purchasing. I will ship it with simple packaging via regular mail.
