This section is designed to hold a screw-in Osmiroid nib in the Pump Pen.
Osmiroid used to provide a wide range of nibs for calligraphers and drawers. While the company closed more than a decade ago, the nibs are still traded and sold.
There are two types of Osmiroid nibs - individual nibs and nibs secured in a plastic screw-in case. This section is designed to hold the screw-in nib.
This section does not contain an Osmiroid nib, since there is no reliable supply. You must use your own Osmiroid nibs in this section.
