In Kaweco's history the Perkeo dip pen appears around 1900. The catalogue of the Heidelberg dip pen factory which was later named Kaweco, describes the Perkeo as a convertible fountain pen.

Today Perkeo is designed to be an ink cartridge fountain pen and a convertible fountain pen. The design stems from the classic Kaweco tradition. The matt octagonal cap and the sixteen-edged barrel harmonise perfectly. The ergonomic grip section inures an effortless writing experience and the colours are awesome.
