Answer:
In regards to pen position, ballpoint pens that use gel ink should be stood upright. This will prevent them leaking. Traditional ballpoint pens that use oil based ink should be stored vertically so the thinner ink moves to the bottom ready for writing. This should make ink flow smoother when it comes to writing.
