These JOWO #6 Nib Units have been tuned to work properly out of the box. Just install on compatible pens and use away.
The Medium and Broad nibs write on the wet side with a line on the broader side of the spectrum. The Fine and Extra Fine nibs are tuned for medium flow and smooth writing.
Some of the pens that take a JOWO No. 6 nib: Bexley, Conklin, Edison, Esterbrook Estie, Faber Castell, Franklin Christoph, Goulet, Taccia, TWSBI, Opus 88 (Demonstrator & Omar), Ranga (some models)
