Overfeed pens

Principal Pump Pen



Draw or letter with a Leonardt Principal nib in our Pump Pen. 

  • Contains one Principal nib and matching feed
  • Replace the nib when it wears down or snaps - slip out the old and stick in the new
  • Use any ink or paint, even India ink or acrylic paint
  • Press the pump when you want a stronger flow - you get what you press, from a drop to a gush. 
  • Large capacity cartridge - draw all day and don't worry about running out
  • Screw-on cap and body prevent leakage

Our Pump Pen is ideal for encouraging the flow of ink or paint. This is especially useful when you want to:

  • Kick start the flow for a new nib
  • Ink in large areas, such as backgrounds and back drops
  • Force more ink or paint for a surge when you want to draw more quickly, flex back nibs or work with quill nibs where the ink flows through the nib tube
  • Work with thicker inks and paints that don't flow easily

You can double the volume of ink or paint stored in the pen by removing the reservoir and filling the body. The reservoir provides a double wall of guaranteed protection, which might be what you want, but it does reduce your carrying capacity.
