Review: Fantastic Pen! - I am a previous owner of a Fisher Space Pen. Specifically, I owned the Bullet Space Pen (Chrome). I lost it after four happy years. I wanted to replace my lost pen with another, and that's when I came across the Fisher Space Pen, X-Mark Bullet Space Pen, Matte Black. Let me tell you why I love these pens. First, they write smoothly. Second, you can put them in your pants pocket without worrying that your body heat will cause them to leak ink in your pocket. They will not leak. If you don't wear a shirt with pockets, then you'll need to carry a pen in your pants pocket (if you wish to carry a pen). I suppose women (or men) could carry a pen in a bag, or whatever, but, that's not an option for me. The bad thing about my old pen (the Bullet, Chrome) was that it was tapered, and had a smooth chrome finish. This made it a little too easy for the pen to slide out of my pocket when I sat down, especially in a car. I "lost" my old Space (chrome) three times before the last time, when I was unable to find it. Enter the X-Mark Bullet Fisher Space Pen: This pen has ALL the qualities I loved about my original Space Pen, plus a few. First, the cap has a clip, and this provides enough of a texture to keep it from sliding out of your pants pocket when you carry it in your pants pocket. Second, you can clip your pen on your shirt pocket, or on your pants pocket, if you're wearing cargo pants, or pants with large openings at the pockets. All of this would be quite irrelevant if the pen itself did not write with quality, so let me say that it does. It writes smoothly, as mentioned, and it writes on many different surfaces that ordinary pens cannot write on, such as plastic lids, etc. It won't replace your Sharpie, but, it will write on a lot of smooth surfaces that will not usually take ink from a ball point. Also, because the ink is pressurized, it does, indeed, write at any angle. This is useful for me because I often jot things down on a legal pad (or whatever) while I am lying down. I have drawn entire schematics while holding a legal pad and writing with the pen upside down. Most pens will quickly run dry at the tip when you don't have them angled mostly downward. The Fisher Space pen will write smoothly at all angles, for as long as you need it to do so. I have owned all of the big names, and most of the small names, and, without hesitation, I can say that Fisher Space Pens are my favorite pen. And, the Fisher X-Mark Bullet Space Pen, Matte Black is my favorite Fisher Space Pen. It is really hard to believe that such a quality writing instrument, with such unique and robust features, is so inexpensive. Plus, they are MADE IN THE USA, and I like that. I have many friends who are in the military, or the police, and are tactical shooters. This pen has become very popular with them, because of the features that I mentioned, and the non-reflective coating that this all-metal pen has. The Fisher Space Pen, X-Mark, Matte Black, let's them easily update the all important "journal," while in the field. In closing, this pen is . . . GREAT!
Review: Best EDC pen - here's why, and why the O-ring is not a problem - Buy this one even if it's EDC and you never intend to use the clip. Space pens are the most reliable pen you can buy at any price. Same refill as any other space pen, so forget any comments about poor writing quality. You could get a bad refill (not likely), but that could happen to any of the line. They are made in Germany and pressure-sealed to assure consistent ink flow. X-Mark comes with a medium point and I prefer the fine, so I always have a few unused refills around. Ordering a few refills wouldn't hurt just to make sure you always have a working version in your pocket. They don't give up prematurely. If it works when you put it in your pocket, it will work when you need it. And the ink lasts way longer than a standard pen This is the best EDC version for pocket carry for 2 reasons. 1. The clip keeps the pen from rolling away. You put it down and it stays there. 2. Being shorter, it vanishes in your pocket, yet the writing length (cap on back) is basically the same because the non-clip versions end is above where you hold the pen, so it adds no value, other than making the pen longer in your pocket. 3. It has all the virtues of any Space Pen. It will not let you down. Forget to cap it? No problem. Let it sit for a year. No problem. Need to write on a vertical surface, no problem.. Wet surface? No problem. As to O-rings: The last few X-Marks I bought (I sometimes leave them on the plane, or give them to people who like what they see) have had not O-ring problems at all. The cap goes on firmly, stays put, and never falls off unintentionally. I believe the problem is solved, but if you happen to love the pen, but the O-ring isn't working for you, the solution is as close as desertcart or your local hardware store: 010 O-Ring - very common size. 010 aerospace o-ring fixes Fisher x-mark cap 1/4" inside diameter (3/8" outside diameter) x 1/16" wall.

## Questions & Answers

**Q: How well does this work in deep space, not just regular outer space?**
A: When viewed from deep space the pen's faint script takes longer to reach the earth.  It's also affected by dark matter which has made us reconsider the location of everything... Otherwise I can write upside down.  The ink is a bit on the thick side and doesn't have a soft glide, but it always works..

**Q: What's the difference between the x-mark and the regular round one?**
A: Depends on which side of the tic tac toe board your on. X-mark makes better X's. Round one makes better O's.

**Q: How does the finish hold up on this pen?  Does it scratch easily where the cap rubs against the back of the pen when in use?**
A: I carried a black space pen in my pocket with a knife and a flashlight everyday for a few years and I can honestly say that the finish held up very well. There are a few small chips in the finish, but otherwise it is in excellent condition. The cap doesn't wear on the pen as far as I can tell. With as much abuse as I put my pen through, I'd say you probably won't have an issue.

**Q: Does this pen come with the clip?**
A: Yes.  The clip a permanent part of the top.  Not sure if it would matter to you but it can't be removed.  This is a great pen.  You won't regret buying one.(3/6/15:  I never realized the clip was removable.  Either way, as I stated before, it's a great pen.  My first one was lost and I immediately ordered another one.  I don't plan to ever be without one.)

### ⭐⭐⭐⭐⭐ Favorite Fisher Yet
*by M***M on July 17, 2025*

This really improves on the others I have by including a clip and a flat area instead of rounded pointy cap end. Good clip retention in shirt pockets and also small enough to fit in most men’s wallet that I own, easy to write with full length pen when cap is removed and placed on top. Good balance and great ink cartridge.
