Kaweco has been creating fine writing instruments since the late 1800's. In the historic catalogue (printed in approximately 1900) of the Heidelberger Federhalter Fabrik, (the original company name), the original Kaweco PERKEO fountain pen can be found. It is described as a "reversible holder".
Today's Perkeo is designed as a universal/standard cartridge fountain pen with a design grounded in the classic Kaweco tradition. The matte octagonal cap and the matte 16-sided barrel harmonize perfectly with each other. With an ergonomic grip that enables fatigue-free writing.
