Principal Small Demonstrator Fountain Pen

A clear Principal Fountain Pen. If you like to draw with a Leonardt Principal nib, keep track of your ink use, and handle a pretty pen, this is the pen for you. 

The pen contains our Principal feed and the Leonardt Principal nib. You can replace the nib easily - just pull it out and stick in the new nib. Close fit, nice ink flow. 

This is a small pen measuring 4.50" capped, 3.75" uncapped, and 4.50" posted (cap on the back). This pen is better for smaller hands. We provide two larger demonstrators, a medium and a large. 

It fits into small pockets, narrow sleeves in back packs, and other tight places. Great for quick sketching on the fly in the field as well as studio work.

You can keep your eye on the color ink you're using and how much is left to work with. You can also see if any ink leaked into the cap before uncapping the pen. 

To fill the pen, unscrew the back, remove the cartridge and fill it, then replace the cartridge and screw on the back. 

You can add five Principal nibs to your order if you are out of stock.

Adjustments you can make

You can adjust the positions of the nib and feed to find the sweet spot for your pen. We try to make the nib and feed fit correctly, but you are dealing with a cheap dip nib.

Don't misunderstand, I enjoy the Principal nib, but it is not an expensive nib and can have some surface irregularities. These might impede the match. Slide the nib back and forth on the feed and slide the feed in and out of the pen until you find the right combination that works for you.
