Principal Clear Demo Fountain Pen

Draw, write and letter with a Leonardt Principal nib fitted to our Clear Demo Fountain Pen. These are clear see-through fountain pens that you fill using a piston. This is the easiest way to fill and empty pens. The Principal nib is a modern version of the famous Principality nib, which was very popular during the "golden age of fountain pens". There are several different modern versions of the Principality nib, including the Hunt 101 Imperial, but the Principal is the most desirable. This nib is enjoyed by lots of artists because of its soft fine tip and great flex for good line variation. Our Clear Demo Fountain Pen is the ideal drawing tool - they're easy to fill using the piston device, and the pen is clear so you can see what you're working with.
