Manufactured by Jowo (Germany) and branded with the Monteverde logo, this stainless steel, #6 nib unit includes the feed and the screw-in housing. For compatible pens that also have a screw-in Jowo housing, you can simply swap the nib by unscrewing the nib unit from the section and screwing in this replacement nib. For other #6 compatible nibs without a removable housing, the nib and feed can be removed by pulling them from the friction fit housing unit.
