Innovation at its best

This pen may be famous for its ability to write in space, but works equally well here on earth for a multitude of applications. Free-flowing ink, no splodges or overflows, and a good, solid black ink colour. It is ideal for use with the tactical pen, as it appears robust.

Quality.

A great product, does everything its says (I havent tried it underwater yet though!). Same thickness line as a black Bic pen, but this has a much darker black and a perfectly consistent flow. Thumbs up.

Great refill, used in Scrade Pen

I purchased this refill along with a Schrade Tactical pen, and installed it immediately, due to the pen's ink being DoA. It's been working well since then, even on paper that is submerged in water.

Quick Delivery - Boss is happy with his new space pen refills.

I was pleased to find these original sku #FPSPR4 Fisher Space Pen refills online at Knife Center. They were reasonably priced and arrived very quickly. My boss says that the ink in his space pen lasted for ages so we used that cartridge sku number. I didn't want to get a newer refill with a different sku because they might not have the same quality. So far, so good with these.
