How to choose the right tip size
- 0.38–0.5 mm: best for smaller handwriting, planners, and detailed notes.
- 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.

Final recommendation
Buy the Uni Jetstream if you want the simplest all-purpose choice. Choose Pilot Acroball if you prioritise a smooth ballpoint feel. Pick Zebra bLen if you want a comfortable, straightforward pen for daily use.
