There is no substitute for the Space Pen (I personally use the bullet style pocket size). It uses a pressurized gasket to push the ink in any position so will writ upside down all day long. It has a great backstory as being an unsolicited proposal to NASA to write in zero gravity [1]. The very best pen gift for any Engineer.

I hated the Space Pen because the ink always felt sticky and it wrote poorly.

Schmidt 4889 is a substitute pressurized refill that is compatible with the Space Pen, although I have not tried it yet.
