Fisher SPR4 Space Pen Pressurized Ballpoint Ink Refill, Medium Point, Pack of 3, Black Ink

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.

This refill works great. My husband uses it in his uzi pen and loves it. It writes on just about anything and from any angle. It flows with ease and there is no leakage. He was tired of his pen needing to be scribbled with before writing to get it started and sometimes skipping. But this refill works every time.

I received the Fisher pen as a gift, and I prefer getting their proprietary ink refills from the manufacturer. The refills perform in any environment, and never fails. Excellent product!

Product fit my Sensa pens. I've had these in the past and the ink flow is great and of good quality.

Here is the pen that I'm using for this refill: https://www.amazon.com/Parker-Retractable-Ballpoint-Stainless-78033/dp/B00112XNJQ With the adapter in place, the refill is about 1/8" longer than the Parker Jotter refill. This caused the tip to not quite recede into the pen, and it was hard to retract and extend. I used a 3/16" drill bit (running in reverse) to deepen the hole in the adapter by about 1/8" which wasn't overly hard to do but shouldn't be necessary. But now it's a perfect fit. It writes like a Fisher should. No complaints there.

Item came in as pictured. I have been using this refill for my pen for a few years, they do eventually run out and need to be refilled. I constantly have to be on the go and write in different angles on my clipboard in different angles, and this really does the job providing constant ink flow. I seem to get more writing out of regular bic pens, but whats the use if it cant write sideways or upside down right? so far I have gone through about 5 refills of these throughout the past 2 years with one of my favorite pens so its definitely worth it. I have once accidentally dropped my pen and just so happen to land on the tip of the refill. This caused the ink to slowly seep out and luckly I was right next to a trash can to just open my pen and throw out the refill. This was something that I have caused myself and not a defect. I will for sure order more when I run low as I will always keep backup refills handy in my office in case I drop my pen again.

My compact space pen finally went dry and since I love the features of it, I got some refills (you can't just toss away a good pen if a refill is an option). It was a perfect fit, I got the correct color and thickness that I ordered, so no complaints. I can't say how long it'll last because I've only put it to light use but it writes well, flows good, and still lets me right at weird angles (sideways, upside-down, etc) which was one of the things I love about it.

Just plain works anywhere and one refill will last until the moon falls out of the sky. In fact I am never without the Fisher Space Pen (3-3/4 inches closed) in my pocket. An engineering marvel. Thanks Fisher.

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%.

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

Prezzo leggermente più caro che in negozio a Milano, per il resto ottimi refill, arrivati addirittura con stampata data di produzione recentissima! ( 11/20 )

Just what I needed
