I loved this pen and thought it was cool, but I'm selling it because I have too many stationery items. I haven't used it very much. I checked to see if it still writes, and it works perfectly. I've confirmed that the silver part of the connection in the middle has the PARKER lettering and mark engraved on it, but I couldn't take a good picture of it. Size: Length/approx. 140mm, Shaft diameter/approx. 10mmφ Function: Knock type Price: 8,800 yen (tax included) Thank you.
