It's a space pen, in plastic disposable format, for a few bucks. Non pressurized pens just never seem all that reliable. They're always dry when I need one... and usually it's rather disruptive. I'm not writing with a pen daily, so I don't notice it's dried until I suddenly need to label something, and now my projects is on hold sifting through drawers for pens.
