Pentel Home Run Mechanical Pencil - Gold Unused. I found this while cleaning up my parents' house, so I'm putting it up for sale. This is a discontinued item that was sold in the Showa era. I think it's a rare item that you don't see very often online. Since it's unused, it's unclear whether it can be used as a mechanical pencil. I would appreciate it if you would consider it for collection purposes. It has been stored for a very long time, so there are fine scratches and dirt. Please check the photos carefully before purchasing. Thank you.
