After reading about it and then seeing it at the local Staples, I decided to go ahead and purchase the Bullet Space Pen in Matte Black by Fisher. Closed it’s a mere 3.75 inches, pop the cap off and attach to the bottom of the pen and it extents to 5.25 inches. The pressurized ink cartridge that comes with the pen is the black medium point. The pressurization allows it to continue to write at any angle.
I bought it for it compact size when closed and overall weight in my hand. They have a version with the built in stylus, but Staples doesn’t stock it. So how does it write? Just ok, it’s like any other medium ball point pen, if you’re into scratchy ball point pens. I am going to order the fine point refills to see if that makes a difference. Until then, it will stay in the confines of the pen holder in my levenger, just in case I forget my other pen.
