Use our Sketch Nib ink feed to draw, letter and write using our Sketch nib in our Classic Fountain Pens, Classic Pump Pens, and Piston Demo Fountain Pens. 

This ink feed is identical to our ink feeds for Brause Rose nibs, Hunt drawing nibs, and all three Manga G nibs. We also call these "Large Nib ink feeds". 

You can slip these feeds in and out of our pens to clean them or exchange them.
