The silver Kaweco Perkeo clip adds functionality and secure transport to Perkeo range fountain pens and rollerball pens. Constructed of durable metal with a bright silver finish, it slides and fits securely onto the octagonal cap of the full-size Perkeo pens. Its metal spring allows you to easily attach the pen to shirt pockets, backpacks, pencil cases or notebook covers without damaging the holder. With a modern curved design and engraved logo, it's the essential accessory to prevent your pen from rolling off the table and to keep it always within reach.
