The Lamy 2000 fountain pen is the company's flagship pen, made of a combination of black fiberglass and brushed stainless steel known as Makrolon. It is piston filled and therefore can only be used with bottled ink and not with ink cartridges. The piston does have a large ink capacity, allowing you many pages of writing pleasure. The Lamy 2000 is so revered that it is on permanent display at the Museum of Modern Art and has won countless design awards. The body of the pen has 4 small ink windows, which allow the user to see how much ink remains in the pen. The nib is a 14 carat gold, platinum plated nib and available in Extra Fine, Fine, and Medium.
