These pens were done on a government contract and apparently there was some left-over stock. CountyComm got a hold of them and is letting them go for about $50 a pop. Sounds expensive, but that price is actually pretty good for what ya get. It’s an all stainless steel body stuffed with the same SPR4 pressurized Fisher ink refill that the Space Pen uses. It’s about 5.25″ long with a diameter of .50″.
