Fine Line Pens for Illustrating and Doodling

Let’s talk about pens. It is a sad moment when you are mid-doodle and your $3 Micron Pen starts to run out of juice. I can’t tell you how many pens I have gone through over the years, but it starts to add up quickly even if you are just a hobby artist. If you’ve been searching for the perfect drawing pen, look no further.

As a frugal artist, I have never been satisfied with single-use paint pens/markers or drawing pens. I like products that last forever, and I am super excited that I found this product. Just like the paint pen I frequently recommend, I found a drawing pen that is refillable, precise, and versatile.

I can’t see myself buying any other pen for a long time. Well–except for all the other sizes of this particular pen…

Rotring Isograph Technical Drawing Pen

This isn’t a new product. Rotring has been around for decades, but I only discovered these pens in 2019. I believe these have been marketed mostly to architects and technical drafters, but I think more artists would love them.

I bought the .25mm Rotring Isograph pen and filled the reservoir with some India ink I already had in my studio, and my goodness is this pen amazing. I used to buy Micron .005 pens (Amazon), but I felt like the ink was a precious resource and my pens would dry up too quickly from all of my doodling. They are great pens, but when I’m afraid of running out of ink, I feel like it gets in the way of my creative process.

Enter the Rotring Isograph Pen, and my fears disappeared. When ink starts to run low, you just open the pen, fill the reservoir, and go back to drawing. Sweet, sweet creative freedom. Now I won’t be chucking single-use pens in the garbage can after a few drawings.

Products I use:

Pen Pros
  • Very precise
  • Pen reservoir is refillable
  • Pen is easy to dismantle, clean, and refill
  • You can customize the colors and inks used
  • Comes in a variety of sizes
  • So far I haven’t encountered any ink burps or pen explosions.
Pen Cons
  • Not cheap. These pens are a bit expensive initially. The .25mm pen I bought was around $25, but it pays for itself after a few refills if you factor in how many single use pens you’d go through over a few months.
  • If you don’t use the pen frequently, the ink can dry in the dip. Just take the pen apart and run warm water through until it clears.
