In Kaweco's historical records, the PERKEO model can be found as early as 1900, in the form of an eye- dropper, in a catalogue of the Heidelberger Federhalterfabrik (dip pen factory).

Today, the PERKEO is Kaweco's entry-level model. It stands out due to its ergonomic grip, octagonal cap and hexadecagon-shaped barrel.

The Perkeo's expressive colour combinations range from light pastels to vibrant and nostalgic colours.
