14k gold nib, ruthenium-plated, made by JoWo in Germany. Typically referred to as a “#6” sized nib.

This nib will fit in all current production Leonardo models that use a #6 size JoWo nib. The nib unit easily screws in and out of the grip section. The nib and feed can be pulled out of the collar for use in pens with an ebonite feed.

Nib comes on its own. The ABS plastic feed and collar are not included.
