## Description

Review: When it absolutely, positively MUST work - When it absolutely, positively MUST work They say a picture is worth 1000 words, so how much is this video saying? So I pretty much think the video says it all but there may be a couple of questions. The paper is simple laser printer paper and a pen is a Zebra F-701. There’s been comes in some of the crappy us staying on earth but it has the fisher space pen refill inside it and it fits mostly it is a little bit tight so if you widen or snip the silicone collar inside the metal tip of the pen , it’s smooths out quite a bit. The liquid is water despite many of my friends determined to believe it is vodka. I suppose it would work as well but the ink might run a little more. Anyway who’s going to waste that much vodka? I’m actually surprised when I run into somebody who’s never used his space pen at some point in their life. Is the ink the prettiest?No. Does it right the smoothest? No. But does it write where nothing else will write and on what nothing else will write? Absolutely. And actually it writes pretty darn smoothly all things considered. I prefer the medium points for smoothness and line is still quite fine. It uses a ceramic bowl in the point and I think that’s responsible for a smoother flow and smoother writing experience than a steel bearing point is. Some people complain that there’s a little difference between the fine in the medium points and maybe you said but I think they’re really missing the point of this pen. I take them camping and hiking. They write in the rain quite well ( I pair them with the “Rite-In-The-Rain notebook ) You can keep them in your car in the heat isn’t going to destroy them. They’re not going to explode in your pocket and they write a lot better on airplanes than my other pens. In my experience the cartridges last a considerably longer time that other ball points as well. The ink never dries up or evaporates. Being left-handed one tends to smudge over the things they write and this is permanent oil base think that dries very quickly so I usually don’t run into that problem like I can with other ball points and fountain pens. I’ve not been impressed with the actual pen construction that Fisher makes recently but the refills are still solid. They’re not cheap comparatively but they’re still affordable. It is far as I’m concerned it’s twice with a regular refill is but I’d last three times as long so it actually is a better value. And this thing does what no other pen made can do . If this is an a five star product then I don’t know what is.
Review: Great refill for an even greater pen - Best pen out there. Writes on any and all surfaces and in any temperature and it's indelible. I just wish they offered an ultra fine point instead of just the fine point. Refill lasts a long time and is easy to buy and use.

## Questions & Answers

**Q: Is there a difference between the spr4 and the pr4?**
A: The "PR" stands for  Pressurized Refill and the PR4 is the black refill that fills most of the standard Fisher Space pens and other similar pens.  If the code ends in a "B", then it's a bold, or ends in a "F" then it's a fine point.  The numeric value after the PR indicates the color (1= blue  2=red, 3=green, 4=black, etc.
I believe that the "SPR" simply means that the package includes the little plastic adapter piece that makes the refill Parker compatible.  All my refills are the SPR version and work in either Fisher Space Pens (without the plastic adapter) or in my Parker Jotter pens (with the adapter).
BTW - Fisher also makes refills with a label "C" like C1 or C4 which are for Cross pens.

**Q: Will this refill work in a Bullet space pen?**
A: Greg K,This refill does work correctly in several Bullet Space Pens I purchased!

**Q: What is the tip size?  I like a solid 1.0, would that be medium or bold?**
A: I would have to say this is more of a medium than a bold.  Most 1.0 pens that I have purchased like the Pilot G-2 or Uniball 207 Gel Impact are bold, which I prefer.  The Fisher Space Pen refill is less so to me, but still good.   What I REALLY like about the Fisher is how exceptionally smooth the ink flow is.

**Q: Will this fit the zebra sl-f1 mini ballpoint pen?**
A: That I do not know.

### ⭐⭐⭐⭐⭐ Changed my relationship with the Space Pen
*by M***. on October 2, 2020*

I've had a Fischer Space Pen (bullet) for years as a backup, go-anywhere pen, and, to be honest, I hated it. The ink was extremely inconsistent. Sometimes it would run spider-web thin and then in the same word it would suddenly lay a fat blob of ink on the page that would smear as soon as you touched it. I used the pen when nothing else was available, but couldn't stand writing with it for anything more than the shortest note. Then someone recommended I ditch the Medium Black standard refill I've been using all this time, and replace it with a Fine Blue. *Shrug* thought I, surely it will still suck. Nope, the Fine Blue refill is amazing. It's way more consistent, hardly ever blobs ink on the page, and just writes way more smoothly (to be fair, some of that "smoothness" is probably from the fact that I'm not constantly changing pressure as the ink flow goes up and down like it did on the old one). I'm really shocked at the difference in writing quality and consistency. And the craziest thing is that I was worried that the "Fine" would be almost invisible considering how the the "Medium" looks at times, but I *cannot* tell a jot of difference between the two in terms of line thickness. This is not like most pens where Medium is substantially thicker or Bolder than Fine. The only difference is one is blue, smooth, and consistent, and the other is a trainwreck. I highly recommend this refill if you're going to put it anything that runs this size cartridge. In particular, I think t's a great cartridge for the Pilot F-701.
