This classic fountain pen is available with a wide range of nib sizes (OB, BB and OBB to special order). It is a piston-filler so uses bottled ink only (but has a large ink capacity) and a small ink window in the barrel keeps you informed of remaining "fuel". Note that Lamy 2000 fountain pen nibs used to run a little wider than other pens but following a change in specification in c.2009 this is no longer the case. Nibs are semi-hooded to prevent ink drying when left uncapped and are made from 14kt gold with platinum plating.
