This black Military Fisher Space Pen is used extensively by the US Armed Forces. The rugged design and consistent operation don't even break a sweat under the insane operating conditions the Armed Forces put them through. It is a 'get the job done with no fuss' kind of pen. Its metal body and matte black coating are durable and simple. One-handed clicking exposes and retracts the ink head. It is ready to go at a moment's notice and will write for sure.

Fisher Space Pens all use the same High-Tech Sealed Pressurized Ink Cartridge. Its specifications are amazing. It will write in all temperatures from -30 degrees Fahrenheit up to 400 degrees Fahrenheit, over most grease, under water, in zero gravity, and at any writing angle.

We're hoping that none of our customers ever have to use these pens at the extreme temperatures, but we know the other features might come in extremely handy.

Since the ink is pressurized at 40psi, you don't have to worry about holding the pen at a proper angle for gravity-fed ink to flow. Its precision tungsten-carbide ball head keeps the ink from leaking out at this pressure.

Fisher Pens were developed for the United States' fledgling space program during the space race. NASA needed a pen that would work in space. Every pen used since mankind invented them had required gravity to pull the ink down onto the writing surface. So Fisher pens invented the pressurized ink pen. It has since been used on every manned US space flight since 1965 (and more recently on every Russian manned space flight).

Not only will Fisher Space pens work in zero gravity, they will actually work against gravity. You can hold it perfectly upside-down and still get a fine, even writing line just as if you were using a fine pen at a normal angle (try this one out for yourself!).

If your work or play entails writing in a messy, machine-oriented environment or a wet environment, the Fisher Space pen is perfect for you. Normal ink pens won't write at all over a grease-smudged piece of paper. Fisher Space Pens don't even realize the grease is there. The same goes for water. A Fisher Space pen will write on a scrap of paper at the bottom of a glass of water.

The Bottom Line: A Fisher Space Pen writes when you need it to, every time, no matter what.

Every Fisher Space Pen is hand-assembled and hand tested. Each comes with a lifetime satisfaction guarantee from Fisher Pens.
