I’ve carried a space pen
I’ve carried a space pen for the majority of my adult life. I discovered them originally when I was an Active Duty Marine and have carried one consistently with the exception of moments where I have lost one. -I’ve never had to purchase a refill, as they seem to last forever. They don’t leak if you fall in the lake or accidentally swim with them. I’ve sent it through the wash numerous times without cause, and I’ve never had one fail.
I don’t carry many “accessories”, but what I do have on me is built for purpose and to last. The Fisher Space Pen is second to none in that regard.
