Kaweco Sport Classic Fine Nib + Rhodia No. 12 Graph Pad
I'm a firm believer in maximizing utility. Perhaps that's why I shied away from fountain pens for so long. They always struck me as overly fancy instruments that tethered the writer to a desk. This pen completely changed my mind! Form follows function here, no doubt about it. It writes smoothly, is lightweight and is perfect for carrying around all day in a pocket. Bravo, Kaweco. You've made a believer of me!
