  • 0.7 mm: a balanced size for most everyday writing.
  • 1.0 mm: best if you want a bolder, more visible line.

Jetstream vs. gel pens

If you are deciding between a ballpoint and a gel pen, choose a ballpoint such as Jetstream, Acroball, or bLen for general-purpose writing. Choose a gel pen when rich colour and a more expressive line matter more. For a direct comparison of two popular Japanese options, read our Uni Jetstream vs. Zebra Sarasa guide.
