Protect your pen with a Kaweco leather case or pouch! Kaweco (Federhalter-Fabrik Koch, Weber & Co) was founded in 1883 as the Heidelberger Federhalterfabrik (Heidelberger pen factory). Based in Heidelberg, Germany, the company has a long tradition of pen making. It was one of the first German manufacturers to employ injection moulding. With a chequered history of closures and resurrections, Kaweco has again been producing fountain pens since 1995.
