An entry-level fountain pen from Kaweco, the Perkeo comes in a range of unexpected colour combinations. It features everything you'd expect from Kaweco - quality workmanship, the familiar octagonal cap and barrel and a stainless steel nib - plus it's reasonably-priced.
It has a comfortable triangular grip and takes standard international ink cartridges. It will also take the Kaweco converter for use with bottled ink.
