Kaweco Perkeo Rollerball Pen Jungle Green

Perkeo rollerball, to match the entry-level fountain pen. It comes in a range of both contemporary and unexpected colour combinations and features everything you'd expect from Kaweco - quality workmanship, the familiar octagonal cap and barrel - plus it's reasonably-priced.

It has a comfortable triangular grip and takes widely-available Euro-format rollerball refills.
