Thank you for viewing this item. Kato Seisakusho Ballpoint Pen Kaleidoscope This item has been stored at home. It is possible to write with it. It is clean. The box cover has some scratches from storage. I have been collecting these, but I will sell them to someone who will use them. This is a celluloid pen from Kato Seisakusho, which will likely become increasingly rare in the future. Thank you!
