The plastic coating of the pen is a solid, the INK inside, that shows what you wrote is a liquid, and there is no gas what-so-ever.
A shaky ball :P

As you know with increasing attitude Atmospheric pressure decreases , so the pressure inside the pen is more compared to the its surrounding Are (i.e inside the Flight).When we are using the pen , the ink gets spilled due to varying pressure.Hence the caution.
the first pen was a feather and ink and they used that idea by thinking about how the ink would stay inside of the bottom of the feather and they used that and made a plastic tube inside of the plastic and used that to create a pen if that answers your question ;P
