Kaweco Perkeo All Black Fountain Pen

<p>Originally released as a dip pen around the year 1900, the Perkeo has been revived as a stylish entry-level fountain pen perfect for students and beginners. It carries on Kaweco's hallmark combination of classy and offbeat styling elements with its octagonal cap, 16-sided barrel, and stealthy all-black color scheme.
