Lamy's flagship fountain pen is the 2000 made of a combination of fibreglass and brushed stainless steel known as Makrolon. It is piston filled and as such can only be used with an ink bottle and not with ink cartridges. The piston does have a large capacity.

The Lamy 2000 is so revered that it is on permanent display at the Museum of Modern Art and has won countless design awards.
