Beautiful limited edition design
The atomic theme is subtle yet striking. Beyond aesthetics, the performance is top-tier. It starts instantly every time I click it, with no hard starts or blobs of ink.

Worth the limited edition price
I collect high-end pens, and this uni Mitsubishi model stands out. The 0.5mm tip provides incredible precision for detailed note-taking. The build quality feels premium and durable.

Perfect for fast note takers
As a student, I write pages every day. This pen never smudges, even when I wipe my hand across fresh ink immediately. The low-viscosity ink makes long writing sessions fatigue-free.

Great writer, unique look
The writing experience is fantastic—very smooth and consistent. I gave it 4 stars only because the clip feels slightly tighter than my other Jetstreams, but the ink flow is flawless.

Excellent daily driver
Switched from my standard ballpoints to this gel hybrid. The difference in smoothness is night and day. Only wish the refills were slightly easier to find locally, but online ordering solves that.

Smoothest pen I have ever used
The JETSTREAM ink technology is no joke. It glides across the paper effortlessly without any skipping. The atomic design looks sleek on my desk, and the quick-dry feature is perfect for my left-handed writing.
Q: Is this pen suitable for left-handed writers?
A: Yes, the New JETSTREAM ink is formulated to be quick-drying, which significantly reduces smudging for left-handed users.
Q: Does the 0.5mm tip write like a fine point or a medium point?
A: The 0.5mm tip writes as an extra-fine line, offering high precision similar to a fine-point gel pen but with the smoothness of a ballpoint.
Q: What makes this the 'Atomic' limited edition?
A: This edition features a special colorway and finish inspired by atomic structures, along with exclusive packaging not found in the standard release.
Q: Is the grip rubberized or plastic?
A: The SXN-150 features a soft, rubberized ergonomic grip designed to reduce hand fatigue during extended writing periods.
Q: Can I use standard uni Jetstream refills with this pen?
A: Yes, the SXN-150 body is compatible with standard uni SXR-89 and SXR-200 Jetstream refills.
