Fisher Space Pen Gas Pressure Refill B SPR1B Blue

Liked it better than the medium point, but I wish it would write smoother. Fisher Space Pen Cartridges are great if you write less than 3 pages of A4 with them.

As Fischer pens go this refill writes as one would expect and that is to write smoothly at any angle and in any weather condition. I purchased this item as I prefer to write with blue ink. I'm not sure if other colours are available but a green and red would be nice to add to my collection.

Ink just as it should be in a fisher space pen. Arrived earier than exspected. Works fine, and fits my pen. Doesn't leak, and starts to write as soon as the pen touches the paper. Really don't think you can ask for anything more of a pen refill.

Smooth and a bit broader writing than the thinner one that comes with the space pen.

Fisher refills are superior to all others. Wish I'd discovered them sooner.

Just the job

Bought for regular,daily use. Not let me down.

this is the ultimate pen for Apollo program lovers
