The Penbbs 350 is a metal fountain pen that is convertible into a rollerball pen.
The Penbbs 350 is an aluminum fountain pen that is sold, in some versions, as a kit that allows it to be converted to be a rollerball that uses fountain pen ink.
Its design is closely related to the Namisu Ixion, with some people conjecturing that they are made in the same factory. The Ixion is shorter and wider than the 350, it also doesn’t post as deeply as the 350. This means the Ixion is a shorter pen overall, but when not next to one another the two look the same.
The Penbb 350 is one of the few high-quality Chinese fountain pens that has a fully metal body.
