These pens get their name "demonstrator" because they demonstrate the inner workings of a fountain pen.Our demonstrators use a piston device to fill and empty the pen. This keeps your hands clean, lets you switch inks quickly, and reveals the amount of ink you have left.

Compared to our black pens

Clear Demonstrators look better, you can see the volume of ink and paint that remains, and they are easier to fill, but they don't work as well with artistic media. If you leave India ink and acrylic paint inside piston filler pens, you run the risk of the media drying out inside the reservoir. When this happens, you have to clean out the reservoir. The reservoir is a sealed compartment that takes several steps to access. We describe how to do this in the user information. We even provide a tool that helps gain access.
