Fisher Space Pen Military Pen -

Made especially for the U.S. armed forces, this rugged pen can write nearly anywhere, on nearly anything.

Since 1967, Fisher Space Pens have been used by American astronauts on all manned space flights.

Made in USA.


  • Replaceable pressurized ink cartridge continuously feeds ink to the tungsten carbide ball, allowing pen to write at any angle--even upside down

Weather and Wind:

  • Thixotropic ink writes smoothly and dependably on most surfaces, even under water, on photographs, in freezing cold, extreme heat and in space!


  • Revolving ball liquefies the ink so that it writes more smoothly, more dependably and longer than most pens
  • Medium point, black ink
  • Stainless steel, precision-machined socket prevents leaks and oozing yet delivers uniform ink flow

I thINK it is so dePENdable, am I WRITE?

My Grandmother gave me my first Fisher Space Pen when I was about 7 years old. It looked pretty cool, but I certainly didn't appreciate a good pen when I was that young. I kept it and used it until I lost it when I was about 15. Now, 15 years later, I bought myself a new one.. this Fisher Space Pen Military Pen. I liked the look and size of it, plus it's pretty cheap. Unfortunately I think the one I got was a lemon. I tried writing a lot, but the ink would cut out very frequently. I drew a straight line that looked like morse code. I exchanged it at REI with no problem (are there ever any problems returning/exchanging things at REI? Didn't think so..). The one I have now writes BEAUTIFULLY. Very, very smooth. No smudges. It's just a good, dependable pen. Also, the description doesn't mention this, but the pen "cap" is fixed to the pen. You twist the cap to make the point stick out for writing.

The only pen you'll ever need

This pen is perfect for someone who shops at REI. I used to be able to get them on base, but I had to move and couldn't find them anymore. REI to the rescue.

In any case, I have used this pen in sub-zero temps on the flightline, while SCUBA diving (it works, but just take a pencil), and in the waterproof journal I kept during a month in Thailand. It's worked perfectly in every situation. Next stop, space...

Only drawback is that it's a metal pen, so if you deathgrip it and write 20 pages, it's going to leave a mark.

Nice features: most waterproof paper has a waxy texture and other pens won't write on it; the whole body of the pen is metal, so you can use it as a MacGyver type tool (it works well as a prybar and box opener); one hand operation beats other Fischers; fits well in pen pockets on uniforms.

Nothing Special, but it's a Good Pen:

There's nothing particularly exceptional about this pen, but it does exhibit solid construction and has a nice matte finish. By far the biggest attribute is the fact that it uses a Fisher Space-Pen cartridge (something that many other pens are able to claim) which allows the user to write at altitude, on nearly any surface, even under water. They are very reliable, but do have some imperfections, mostly inherent flaws of ballpoint pens including the requirement of greater writing pressure than a rollerball or fountain and having a less smooth flow. OTOH Fisher designed a better than average ballpoint (that operates in conditions that do not permit the use of a rollerball or fountain pen), so I have no complaints.

Great Pen!!!

I've found that this is a very convenient pen, and it is perfectly at home in anything from a flight suit pen sleeve to the spirals of a notepad. Overall I think it is an amazing value, much more convenient to me than the bullet pen, albeit a small sacrifice on space. Five stars, amazing product.

The only con is a small blob of ink after you haven't written anything for a while. This is due to the pressurized cartridge. I don't notice it because when I take notes, I do not care if the header has a small blob of ink or the like.

nothing is perfect

Got mine in November 2011 in the Boise store. Luckily I bought a spare refill cartouche with it because the black cartouche that came with it only lasted 9 weeks. Mind you I am not an author so I am not using it above average. The spare cartouche is blue. See how long that one lasts. Both the black and blue smear easily. Nonetheless I'd buy this pen again and recommend it to my friends.

The HumVee of Pens

These pens are built bomber tough to hold up in outdoor conditions. You can write at any angle, even upside down or up against a wall, without skipping or shaking. I have them stashed in a number of places so whenever I have to write important stuff down I have one handy. Pair this with the Write-In-The-Rain pad for a fantastically durable note and info taking set up.

Best Pen Ever!!!

I picked up this pen out of curiosity and because I wanted something reliable when I am out signing geocaching logs. This pen is incredible. It feels great in your hand, it glides smoothly across surfaces, and the ink never dries out!

The pen quickly shifted from my geocaching backpack to my front pocket and travels with me everywhere now.

Best Pen Ever!!!

As a Paramedic I work in many different environments. I need pens that are reliable in any weather and anytime. The Fisher Pens are the BEST!!! No other pen I have used performs as well as the Fisher Space Pen!!! I own three of these and I am sure I will buy more!!!

I hate this product...

...because I've stopped carrying my Mont Blanc ballpoint and my Waterman fountain pen w/italic nib!These are just really nice pens for [$]. Bomber, convenient, comfy. Just as happy writing field notes in the rain as taking notes in a meeting.

Great all around pen.

A bit on the heavy side, but also indestructable. I use it every day. Great value. The original fill is still going strong after more than three months. One hand operation sold me on this model over the other fishers.

Neutral Reviews:

Close, but has drawbacks

The black matte finish is not grippy and the pen feels a bit too slippery for easy writing. I would choose a different Fisher model because of this.

The space pen refill may write well in extreme conditions, but the drawback is that it tends to glob when it first touches the paper and can skip a bit. Under ordinary conditions, most other ball point pen cartridges are better than the Fisher space pen cartridge. I would recommend it only for extreme use.
