This is the Kaweco Perkeo fountain pen in the transparent "All Clear" colorway.
Kaweco Perkeo fountain pens are - in my opinion - fantastically underrated "starter" fountain pens: low-cost, lightweight, and comfortable in the hand. The Kaweco Perkeo's modern, slightly faceted grip helps keep your hold relaxed and steady, making it an easy pick for new fountain pen users and longtime writers who want a no-fuss daily driver. Clean lines, fun colorways, and a surprisingly smooth writing experience—Perkeo is pure practical charm, and doesn't get the love it deserves next to the Pilot Kakunos and Platinum Plaisirs of the world.
