I've been slowly filling up a little pocket book that I carry around with me everywhere I go. Back in August when I was trekking around downtown San Fransisco I was told to visit Maido to check out their selection of pens. I've stuck with ballpoint for a while now to doodle around with until it became my favored go to pen. I picked up some 0.3 and 0.5 Hi-Tec C's there and they're incredibly fun to use. In the beginning they seem to never run out of ink, and can produce crisp, thin lines or peppered dots, whichever way it's held.
