What is the difference between a Mont Blanc and Rolex Pen?

I am trying to write a copy strategy for a copywriting class, but I cannot find any information on these two pens. Can anybody please tell me what the difference is between them? Price, quality, style? Basically, what makes you buy a Rolex Pen instead of a Mont Blanc?|||I don't see the difference... they're just pens and I would really get pissed if after paying that much money they will get to a point where they're not functioning properly... Have you considered the old fashioned BIC? they're kick *** :P|||Brand name is the difference.|||Once is labeled as Mont Blanc and the other as Rolex
