Thank you for viewing. Photo 3 → This is a work by Kentaro-papa, a specialist wooden pen tray artist. It's for 10 pens. There are no attachments. Please check the photo of the back in the second image. Photo 4 → This is a pen tray for 6 pens. I liked the wood grain and kept them for purchase/display, but I have purchased a new pen box, so I am selling them to organize my collection. Please look at the photos carefully and make your decision, and I would appreciate it if you would consider purchasing. These items are stored at home, so please refrain from purchasing if you are concerned about minor details. No claims, no returns, and no cancellations, please.
