Jowo Compatible Special Grind - Broad-Stub (0.9mm - 1.0mm)
Osprey Pens introduces Jowo compatible special grind nib: Broad-Stub
Stub: A Stub nib tipping material is ground flat on the end. This type of a nib produces a narrow line on the cross stroke, broad on the down stroke. It mimics calligraphy (without doing anything different!) unlike flex nibs, which require pressure to change the line width. A stub nib is (usually) a broad nib that has a flat end but smoothly rounded corners.
These Nib Unit works with pre-filled ink cartridges or with bottled ink using a generic international converter
These units will not fit your regular Scholar or Milano fountain pens, as they are made specifically to match a JOWO thread pattern.
