Gillott 303 Piston Demo Fountain Pen

Draw, write and letter with a Gillot 303 nib fitted to our Clear Demonstrator Piston Filler Fountain Pen. These are clear see-through fountain pens that you fill using a piston. This is the easiest and cleanest method to fill and empty a pen. The Gillot 303 nib is enjoyed by lots of artists because of its soft fine tip, tremendous flex, and great line variatioin.
