Fits Zebra F-701 perfectly
Fit perfectly in a newer "all metal" Zebra F701. If using this for that purpose, you will discard the plastic piece that comes with this item. I didn't have to modify anything - just swapped the spring over. No binding, no removal of any pieces inside the pen, no spring trimming, no issues at all.

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.

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.

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

Reliable and long lasting.
My favorite replacement cartridge. Lasts a long time with daily use. Good price. I use it with my favorite pen that I've had for over 14 years.

Just what I wanted.
Very pleased with this bold Fisher Space Pen refill. Prefer bold ink over fine or medium.

Probably More worth it if writing in space, or greasy surfaces, but a great refill either way.
I received this October 6 '25, and it lasted without worry until ~July 6 '26 of light to moderate use almost every weekday since I got it. It will smudge if touched too quickly. I might try a finer tip next time. Not sure if I'd have lost the same amount of money in cheaper everyday pens since then, but it was nice to experience it. Pairing it with a SmootherPro pen showed me how much I appreciate my pens not bending as I write compared to a normal Bic, and not having a wiggly tip like some fancy-looking bulk marketing pens from vendors or distributors that get their brand stamped on them for promotional distribution.

Superior blue ink
These refills are great. I may be a bit snobbish in that I like to know I'm writing with a pen that can write upside down and in water. However, I got to say the ink is a nice blue I like. Would I buy this again? Definitely, and I've bought another 3 refills as they do not cost much.
