Fisher Space Pen 3 Pack Black SPR4 Refills for Bullet

Great refill for my Fisher Space Pen. Writes well.

Official Fischer refills. Great product and fast delivery.

Good price. These are a relatively niche product I think so not much to compare them to. They do seem to write on nearly all surfaces. Would recommend for use in every day carry pen.

Not as easy to write with as previous purchases. Writes at all angles, but needs to be fairly square to the paper to write smoothly. Not had that problem before with Fisher refills. Update - we gave up on that first refill of the pack of three and threw it away - the other two are good.

If this is your question: -You: 'Will this refill fit in my Space Pen?' I'll save you some time: -Me: 'Yes, yes it will' The SPR4 fits in ANY Space Pen with the exception of one: The Q4; The Q4 is the multi-ink Space Pen that has red ink, black ink and a pencil. So if your space pen writes in only one colour and hasn't been hiding a pencil lead for the time you've been using it, this is the refill for you (assuming you want black ink, in a medium gauge). I'm not a Space Pen geek, the following is the sum of experience of using the product daily and about 5 minutes of research. These are genuine Space Pen pressurised refills with black ink. They have a medium-sized ball in the tip - this ball is 1.1mm in circumference (and made of tungsten carbide). The first of these refills actually writes slightly better than the one that came with my Space Pen, giving a more comfortable 'glide' over paper and plastic. It writes well on a range of surfaces and at any orientation, allowing you to use a vertical wall to lean on if you need to. Not being an astronaut, I can't tell you if it writes in space :( Some basic information about Space Pen refills that you may find useful: SPR1 - Blue Medium SPR1F - Blue Fine (0.9mm) SPR1B - Blue Bold (1.3mm) SPR2 - Red medium SPR2F - Red fine SPR3 - Green Medium SPR3F - Green Fine SPR4 - Black Medium SPR4F - Black Fine SPR4B - Black Bold refills available in one size*: SPR5 - Burgundy, SPR6 - Purple, SPR8 - Brown, SPR9 - Turquoise, SPRSL - Silver (*I don't know why there isn't an SPR7.)

I order these either 3 or 6 at a time which lasts nearly a year. Fisher space refills are a little bit niche as they are waterproof and guaranteed to write, as I write all day everyday and the nature of what I write it is absolutely essential that I have a quality working pen.

Do what they're supposed to do. A 3 pack makes sense.

these are the real ones to buy

Best refills, Recommended 100%.

Es ist der Lieblingsstift meines Freundes. Nach ca. 4 Jahren funktionierte die alte Mine nicht mehr so ganz reibungslos. Ich bin froh das ich Ersatz bekommen habe und jetzt schreibt der Stift wieder super gut.

Greatly constructed and very sturdy. Using them on my Parker pens and my Ridge pen. What I most love about these refills is that they write even upside down and so smoothly. Best refills. Look no further, just get this and enjoy it’s quality. Reccommended 100%.

I keep a small Fisher space pen in my wallet. It's an excellent pen for everyday use. I keep it in my wallet in case I need to jot a quick note, address a letter, or the waiter forgets to bring a pen with the credit card receipt. It just works and most of the time I forget it's there. I realized in 2021 the same pen has been in my wallet since 2005. The embarrassing admission: When I realized I never refilled my pen ink after 16 years I ordered these refills. When they arrived I looked at the package, saw they were too long for the pen and cursed my not noticing when I ordered them. I kept them because they were just too small an item to bother returning. I figured maybe someday I'd get a full size Fisher pen. This month I found them in a junk drawer and realized the plastic bit that made the refill "too long" wasn't attached. It's needed for the full size pen, not the small one I ordered it for. By the way, the pen I ordered the refill for STILL hasn't run out towards the end of 2024.

Este tipo de bolis, es una apuesta segura , si no quieres que te falle en el peor momento. Que si, que ya sé que los rusos lo resolvieron con un lápiz, pero con mis años ya no puedo escribir, depende que cosas, con lápiz, si no que requiero de tinta como los adultos. No te fallará, ni en invierno a bajo cero o a 60 grados dentro del coche, siempre va a escribir
