The Ahab flex nib fountain pen allows you to achieve line variation when you apply pressure when writing. This pen is a demonstrator style and has a clear barrel so you can see your ink inside. This pen is made from a biodegradable resin and may show some particles in the resin. It comes with a slide style piston converter.

Noodler's pens are best suited to the experienced, hands on fountain pen user as some adjustment may be required
