Fischer Space Pen ink refill
This is a very nice product at a great price that works well and gets delivered fast.

You get the value you pay for.
Still the quality I found in the late 1960s. Made in the USA in NV. As claimed, writes in any position and on poor-quality paper. Ink is bold and lasts for years with occasional use. The small size when closed, all-metal, smooth surface pen rides comfortably in a front pocket. You get the value you pay for.

VERSITLE, EFFICENT AND SUPERIOR TO CONVENTIONAL REFILLS.
These pen refills fit the Schaeffer Jotter pens and are superior to Schaeffer refills. They will also fit the Rite-In-The-Rain pens. Note: Fisher makes the pressurized Rite-In-The-Rain refills for that brand pen. The Rite-In-The-Rain BK-16 bolt-action pen is my favorite EDC PEN.

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.

A good refill
Writes as expected and it’s a good price. The line is nice and thick and the writing is nice and smooth, and it fits in the pen correctly

An Original Refill for a Unique Pen!
I've had this pen for years and decided to get a refill for it. Forgot what a great pen this is. It is an original Fisher refill so the writing quality is excellent. Fast shipping and good packaging. Would highly recommend.

Works Great! Plus...
The pen refill works very well; exactly as advertised. In addition to fitting the space pen, it also fits into the Zebra F-701 Stainless Steel pen, with a quick (1 minute) alteration to the pen tip bushing. The advantage of using the space pen replacement cartridge into the 'off brand' body combines the "write any where, any position, any time" functionality of the space pen with the near-tactical, rugged, stainless steel, knurled grip Zebra pen. Combining the two results in a pen with the best qualities of both. Zebra F-701 cartridge replacement: The F-701 has a soft plastic bushing inside its pen tip. This bushing has a tapered inside diameter, which gets smaller as it approaches the tip of the pen. Before putting the space pen cartridge into the zebra pen, unscrew the zebra pen tip from its body, and push the space pen cartridge tip into the Zebra pen tip BACKWARDS. This will unseat the internal bushing so it can be easily removed. Cut the bushing with a sharp exacto blade or sharp scissors, removing about 1/4 of its length, from the tip (small) end . Then, slide the space pen tip through the (now shorter) bushing. It should slide through and back with no resistance. If it feels tight, trim a bit more off the bushing. Repeat until the new cartridge tip does slide to and fro, with little to no resistance. (Any resistance can cause the pen to not click open or closed successfully.) Re-assemble the zebra pen, using the F-701 pen body, spring and bushing with the new Space Pen cartridge ( but NOT the included spacer) to create a ruggedized version of the Space Pen. (Note: In addition, the existing Zebra F-701 pen uses the same cartridge as any Zebra F-401 pens that you may own and use.)

Subdued green . The cartridge has the good characteristics of the other colours I have tried.

For my small journal pages it is nice to have a thinner line. All these cartridges give a very smooth writing experience and no problems with ink flow.

You know what, it's just a pen ink; but when this turned up in the post, I was in the middle of a pretty terrible Friday at work. So I'd just like to say thanks very much to "M" for the note on the invoice. It really made my day and restored some faith in humanity. Product wise, I've been writing with Fisher Space Pens for over 25 years. Genuinely a super impressive product which features pressurised ink meaning you can write at all sorts of angles and the pen will continue to write. Haven't had the chance to test it in space but can confirm, they've always worked for me over grease and even underwater/over wet surfaces. Comes with a handy adapter to fix most parker pens too.

Anni fa mi hanno regalato una bellissima penna tattica del marchio Colt che uso anche come penna in caso di necessità, da diverse ricerche sul web ho trovato che questi refill sono i migliori e adatti alla sostituzione dello slot dell'inchiostro e così è stato, è perfetta, per sfizio ho voluto provare il color marrone e scrive benissimo!
