Thank you for viewing. This is a Star Alliance stamp-equipped ballpoint pen, a ''limited edition'' product that is no longer in production. As shown in the image, the pen tip extends about 11cm to reveal the writing point. I have never used it, and it was given to me by a relative. It seems to be quite old, and its rarity is likely high. Ballpoint pen, stationery, stamp, limited edition ※ Since it was given to me by a relative, the stamp part says "Hanji." Apparently, it can be changed.
