Frequently Asked Questions
Who is the 0.38mm Jetstream 4+1 best suited for?
The 0.38mm model is tailored specifically for users who write small, detailed text in pocket diaries, dense Japanese planner grids (like Hobonichi or Jibun Techo), and financial ledgers.
Does the 0.38mm tip feel scratchy on paper?
Unlike conventional micro-fine ballpoints, Uni’s low-viscosity Jetstream hybrid ink lubricates the ball rotation, ensuring a remarkably smooth glide even at 0.38mm.
Can the refills be changed to 0.5mm or 0.7mm later?
Yes, all Uni SXR-80 multi-pen refills share identical physical dimensions, allowing you to freely mix and match 0.38mm, 0.5mm, and 0.7mm refills in the same pen.
