Stationery set from the Johnny's group "Otokogumi" sold in 1988, including a clear file, eraser, and marker pen. Unopened. I bought this when I was a child and kept it stored away. Since it's unopened, I don't know if the pens still work. Thank you for your understanding. This is a dead stock item. Thank you for looking. I also have other valuable Johnny's goods for sale, so please take a look.
