Clear demonstrators are attractive clear pens that let you see into the pen and keep track of your ink quantity. Our large demonstratrors 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. These pens get their name "demonstrator" because they demonstrate the inner workings of a fountain pen.

Select your feed rate
Standard flow feed works with most inks and paints
Rich flow feed works with thicker inks and paints, including traditional India ink and acrylic paints
We recommend the standard flow feed for most inks and paints. Use the rich flow feed only if you are working with exceptionally thick inks.
Polishing Sketch nibs
Sketch nibs are similar to traditional fountain pens and last much longer than dip nibs. Paper is rough, so your Sketch nibs will need polishing from time to time on the underside of the tip.
You can use lapping paper to smooth your Sketch nibs, or you can use a piece of paper from a brown bag. Tear off a section measuring two or three inches to a side, wet the paper, and draw lazy circles and figures eights, then test the nib on your favorite drawing paper. Usually a few seconds of polishing is sufficient. Avoid over polishing.
You can also reshape the tip with more vigorous polishing if you want a special effect, such as left oblique or stub.
Other nibs you can use
- Slip in the Zebra Manga G, Brause Rose, most other Brause nibs, many Osmioid nibs, and selected Hunt nibs including the 22B, 56, and 101
- Use our Nikko/Tachikawa feed and slip in the Nikko and Tachikawa nibs as well as the Principal nib
