Update – The refills I’ve found online so far all seem to be said to fall out of the pen. This is not the “Stylus Pen”, and the correct name is “Telescopic” pen, not “collapsible” as I said in the title (sorry about that).

I don’t know if they still make it or not, but Zebra used to make a collapsible pen. I really liked them because they wrote well, had a medium BP cartridge, and they expanded to a nearly full sized pen when extended. I used to put them in my FAK, and in my EDC pocket organizer.

Yesterday I checked these pens and the ink cartridge in one of them is dried up. It’s an odd looking cartridge. Anyone know where I can get another?

Yes, I know I could just use a Fisher space pen, but I have really big hands and those are hard for me to write with, which is why I liked this Zebra pen so much. It extended from about 2″ to about 4″ when deployed, so it was really handy.
