Ballpoint Pens

Q: What exactly is the difference between a ballpoint pen and a gel pen?
A: It comes down to the ink inside. Ballpoint pens use oil-based ink, which is thicker, dries almost instantly, and lasts forever. Gel pens use water-based gel ink that’s more opaque and vivid but takes a moment to dry. If you need a pen that writes on glossy receipts and won’t smudge under a highlighter, ballpoint is your friend.
Q: Which Japanese ballpoint pen models should I try first?
A: The three you’ll hear about constantly: Uni-ball Jetstream (the king of smooth, available in endless tip sizes and body designs), Pilot Acroball (slightly more tactile feedback, excellent grip), and Zebra Surari (often very affordable, with a rich ink laydown). For a more premium pocket pen, the Pilot Acro 1000 or Uni Jetstream Prime are lovely everyday companions.
Q: What tip sizes do Japanese ballpoint pens come in?
A: The sweet spots are 0.5mm for precise, small handwriting, and 0.7mm for a buttery, bolder line. You’ll also find ultra-fine 0.38mm Jetstreams for those micro planner grids, and bold 1.0mm for signatures or addressing large envelopes. My personal daily driver is a 0.7mm Jetstream — smooth enough to make you want to write more.
