The brass fountain pen is particularly sustainable.It is made entirely in Germany from the well-known eco brass and only has to go through very short transport routes.The brass used is lead-free and, as it is untreated, an individual patina develops over time with use. With 9.7 cm when closed, only 8.7 cm when open and 12.5 cm with the cap screwed on, the Liliput is one of the smallest fountain pens in the world.
