Description

This method of flex nib was invented by myself. It involves 2 nibs. One serves as an overfeed. The other is cut to proper geometry to give ample flexibility. I will let the video speak for itself.
This is a listing for the nib unit alone.

First flex nib, and I love it. Super easy to use and flows great at.

Simply put, the best modern flex nib I own. The nib flexes easily from .03 mm to 3mm with little pressure. I collect vintage and modern flex fountain pens and Im always scepticle when newer products are released. With that said, this nib is the real deal. No railroading, no skipping, and an excellent wet nib. If you enjoy vintage/modern flex pens, don’t hesitate to buy this nib.

This nib definitely has a learning curve, but once you figure out how to get it to flex it’s a beautiful thing. It produces hairlines just as thin as my vintage Waterman’s nibs and downstrokes twice as thick.
