About our Classic Fountain Pens

Our Classic Fountain Pens let you use popular drawing nibs in a fountain pen, not bother dipping the nib. They are durable and designed to last a lifetime.


  • Use any ink or paint — nothing sticks to the pen, so they're easy to clean
  • Large capacity ink reservoir — draw all day and never run out
  • Replace the nib easily — slide out one tool and slip in the other
  • Designed to fit the most popular large drawing nibs
  • Use adaptors to extend the range of nibs and tools you can use

Our pens are fun to use, easy to clean, and hard to plug.

Anatomy of a Fountain Pen

There are three pieces to the Classic Fountain Pen:

  • Cap
  • Body, which contains the nib and feed
  • Barrel, which houses the reservoir

The cap and barrel screw together for a tighter fit without leakage.

Expand Your Carrying Capacity

You can double the carrying capacity of the pen by removing the cartridge and filling the pen body with ink or paint. Doing so removes the "double wall protection" provided by a cartridge, but the screw seal on the body is tight, so there is little risk of leakage.

How To Fill Pump Pens

Filling the Pump Pen is easy:

  1. Unscrew the pen in the middle so you can see the reservoir.
  2. Remove the reservoir.
  3. Fill the reservoir with ink or paint.
  4. Insert the reservoir back into the front of the pen.
  5. Screw the pen back together.

If you have trouble filling the reservoir, here are a couple of tricks:

  1. When you remove the reservoir, wiggle it first to dislodge the mouth of the reservoir from the seal. Ink and paint can dry out and make the reservoir stick.
  2. Take care where you lay the pen after removing the reservoir. The pen still contains ink or paint, which can leak out. If you leave the pen horizontal, such as laying flat on a desk, you might have enough time to fill the reservoir and re-insert it before any ink or paint leaks out.
  3. When you fill the reservoir, don't fill it to the top. Leave a 1/4" (0.65 cm) of free space. If the pen is full of ink, the burp might come out of the front end.
  4. When you insert the reservoir back into the pen, twist the reservoir to seat it. You should feel the reservoir stop snugly inside the pen.

Make sure you replace the back cap and seat that correctly.

Shake the pen a couple of times to get the flow going. Tilting the pen back and forth can also work. Sometimes you have to flick your wrist.

Keep a backup reservoir filled and ready. Fill the capped reservoir with the ink and paint you want to use. This way, when your pen runs out, you can remove the old reservoir and insert the new quickly. Switch the cap from the new reservoir to the old reservoir so the old reservoir doesn't leak.

Pressing the Pump

The pump function is a major advantage of our unique Pump Pens. You press the pump to get a stronger flow. You get what you press — from a drop to a gush — which is why they’re often considered some of the best drawing pens.

You can press the pump on these unique pens several ways depending on how you hold the Pump Pen.

The Normal Grip

Pressing the pump

The most comfortable method is to grip the Pump Pen in what I call the normal manner using three fingers: your thumb, index finger, and middle finger.

Position the pump under any of the three fingers. If you position the pump under your thumb or index finger, you can press the pump directly with the finger. Don't press too hard or press repeatedly as you might move the position of the Pump Pen and alter your drawn line.

Easy Grip

Pressing the pump all three fingers

A better method is to position the pump on top of your middle finger, which wraps around the bottom of the Pump Pen.

Normally, your thumb and index finger cross at the level on the side of the Pump Pen. This means you don't see any pumping action. You make very little conscious effort to pump. You just squeeze the Pump Pen gently with all three fingers, and out flows the ink or paint. The action soon becomes unconscious. We consider this the ideal method for pumping.

Brush Pen Grip

Pressing the pump upright

The Brush Pen Grip method is effective only when you use the Brush Pump Pen because the Pump Pen is held in the vertical position. But this only works with a brush.

You can press the pump with your index finger.

You can press the pump with your thumb depending on where you position the pump, which position feels most comfortable for you.

Both fingers are strong and can expel a lot of ink. This is a good method for inking in large areas with the Brush Pump Pen. Just puddle out the ink and spread it around.

You can always use the three-fingered grip with the Brush Pump Pen when you want to monitor the flow of ink more closely.

Cleaning Pump Pens

Our Pump Pens are easy to clean. Just open them up, flush them out, and put them back together. You can push out the feed and look clear through the body. Doing so makes it easy to clean and hard to plug up, which is ideal when you are working with permanent artistic media, such as India ink and acrylic paint.

If you've used permanent media, such as India ink and acrylic paint, that has dried inside the pen and plugged it up, you need to do a little more work. No need to worry. Nothing will stick inside the pen permanently.

  1. Remove the nib and feed from the front of the pen or the adaptor and clean all parts.
  2. Unscrew the front from the back of the pen, remove the reservoir and clean.
  3. Flush water through the pen parts. If water does not run freely, you have more work to do.
  4. Hold the pen up to a light so you can see through it. Try to discern if there is a partial obstruction. Try to flush it out with more water.
  5. If that doesn't work, stick a stick, such as a chopstick, into the pen part until you feel the obstruction, then wiggle the rod until you free the obstruction. Poke out the obstruction or flush it out with water.
  6. If that doesn't work, soak the plugged pen part in warm, soapy water overnight.
  7. If that doesn't work, try a stronger solution, such as a household cleaning liquid like 409.
  8. If nothing works, return the product to Ackerman Pens, and we'll clean it for you.
