Large Demonstrators

Demonstrators are attractive clear pens that let you view your ink supply and ink flow in real time. They get their name because they demonstrate the inner workings of a fountain pen.

Demonstrators are ideal for artists because they let you check to see what color ink or paint you're working with, view the capacity and gauge when to refill, and present themselves as attractive objects to hold in your hand. 

  • Large capacity
  • Crystal clear
  • Piston filler with two extra seals you can use to replace the seals if they wear down or plug up - include instructions
  • Measures 5.25" uncapped, 5.5" capped, but you can't post this pen (put the cap on the back) because of the piston turn knob
  • Packed in its own metal box

This is the largest of our demonstrators. We offer three sizes of demonstrators
