JINHAO Knock-Type Fountain Pen It is marked as MB, but it feels finer than European F nibs. I purchased it here, but I am selling it because I don't have many opportunities to use it. Currently, it is filled with Pelikan Edelstein Sapphire. If you would prefer it to be cleaned before shipping, I can clean it and send it. (This will take 2-3 days.) If you have no specific requests, I will ship it as is. I bought it because I wanted a knock-type fountain pen, but it didn't suit me very well. I think the knock feel and texture are good. It is a beautiful item with almost no scratches. The box has some damage, particularly around the opening.
