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. Kaweco added a rollerball to their Kaweco Perkeo series in February 2021. The Perkeo rollerball offers great quality at a great price, which makes it ideal for beginners in school or the field of high-quality writing. Visually, the octagonal cap and the 16-sided barrel harmonise perfectly with each other, as the different angles of the surfaces create a unique play of light and shadow. The ergonomic grip section and the low weight of the pen support the writer's posture and allow fatigue-proof writing fun. The Perkeo rollerball comes with a 0.7mm black EURO Refill. A 0.4mm EURO refill is also available to buy separately Refills available here About Kaweco Since 1883 Kaweco have been making high quality writing instruments in striking designs.
