A Gillott 303 nib in a fountain pen! Artists love the Gillott 303 for it's very fine line and delicate flexibility. This is one of the oldest nibs still in use, and it's very difficult to feed ink to correctly. 

This Piston Demo contains a Gillott 303 nib and matching feed. You can replace the nib and feed easily - slide out the old and insert the new. You can use other nibs and feeds listed below. 

Our Piston Demos are attractive clear pens that let you see into the pen and keep and eye on the ink you are using and that quantity that remains. These pens get their name "demo" from "demonstrator" because they demonstrate the inner workings of a fountain pen.

Our Piston Demos use a piston device to fill and empty the pen. This keeps your hands clean and lets you keep track of the color ink you are using, how much is left in the pen, and switch inks quickly. You can remove the piston device to clean the inside of the pen.  

You can add Gillott 303 nibs to your order.
