Uni promotion print ad

A pen with a 0.18mm ball point for writing tiny words. The ad uses a demonstration approach to show how small the words can be written by this pen. It comes with a small word writing competition too. But come to think of it, why do we really need this pen ? I can't think of any practical reason other than using this pen to enter the competition or breaking some world's record. It looks like a product invented purely for technical breakthrough sake.
