Extreme Cold Pen Test - 2021

Living in the northern US, I had the ‘opportunity’ to test 20 pens in sub-zero temps this past weekend and put these popular pens through the ultimate cold-weather test. This is a follow up to my original post two years ago that you can find HERE.

I tested 20 pens all together over a three day period where the temperatures didn’t go above 7 degrees and dipped down to -15 degrees at night. I tested all the pens before and after in the same notebook, which is my new go-to favorite notebook, the Thinkers Notebook.

The pens did very well through this test which I am fairly surprised by. I assumed the marker pens or at least the fountain pen would freeze up.

Included in the test are:

  • 4 Gel Ink Pens

    • Uni-Ball Signo 207

    • MUJI Gel Ink .5

    • Uni-Ball Signo UM-151 .5

    • Uni-Ball Vision Elite

  • 2 Rollerball Ink Pens

    • TUL Fine Tip

    • Retro 51 - Schmidt Easy Flow 9000

  • 4 Marker Tip Pens

    • Staedtler Fine Liner

    • Sakura Pigma Micron 08

    • Papermate Flair Felt Tip

    • Copic Sketch Marker B00

  • 4 Permanent Marker Pens

    • Sharpie Extra Fine Point

    • Sharpie Fine Point

    • TUL Permanent Marker

    • Milwaukee Fine Point

  • 1 Fountain Pen

    • TWSBI Go with Noodler’s Apache Sunset

  • 5 Ballpoint Pens

    • BIC Cristal Ballpoint

    • Field Notes Ballpoint

    • Pilot Frixion Erasable Ballpoint

    • Generic Hotel Ballpoint Pen

    • Fisher Space Pen

It is hard to believe the fountain pen didn’t freeze. I suspect that the TWSBI Go pen was not able to fully freeze and from my prior test, I know that the water-based fountain pen ink does freeze if left out long enough. I wish I had an infrared thermometer to get the temperature of the plastic because it was ice cold and had frost on it when I was checking it!

There was one pen that did not brave the cold and I couldn’t get it started again until it had time to thaw out, which was the MUJI Gel Ink .5 pen.

There is one pen that I did not worry about at all, but still wanted to test, which was the Fisher Space Pen. This one is a custom made pen from Triple Aught Design.

In summary, I know that pencils are the best option for cold temps, but pens are quite resilient to cold weather so are still an option.

If you feel like I have missed anything, or want me to try any other pens, please let me know!

As always, I didn’t receive anything for free in this review, nor do I advertise on this blog. My opinions are my own.

Cheers,

Does this mean pencils are better than pens..?
