Thank you for viewing. This is a Nohara Kogei Old Type Fixed Lead Sleeve Silver. I purchased it but am selling it because I don't use it. There are no lead clogs, and it works without any problems. It is a used item, so there may be small scratches. If you purchase it together with the Nohara Kogei old type mechanical pencil I am selling on this account, I can sell it for 45,000 yen, so please comment if you are interested.
