If you are looking for what is arguably the best pen on earth then Mont Blanc pens are probably what you are looking for. This is because Mont Blanc pens are made with really high quality components, and they are built with precious metal, and in many cases (depending on what model you go with), they have precious stoned in them too. In most cases only the rich can afford a Mont Blanc pen, since they sell for around $300 and up. This is far more than the average consumer would ever want to spend on a mere pen. However, some fountain pen collectors may buy a Mont Blanc fountain pen just to add to their collection of fine pens.
There are tons of models to choose from when it comes to the Mont Blanc pens. A search on the internet will show dozens of different styles of the Mont Blanc, so you will easily be able to find what you are looking for. They make both ballpoint pens and fountain pens, along with a few metal pencils.
