Frequently Asked Questions

What makes Jetstream hybrid ink different from standard ballpoint ink?

Uni Jetstream ink blends high-grade oil solvents with ultra-low-viscosity pigments. This allows the ball to rotate freely with nearly half the friction of traditional ballpoints, delivering intense color saturation without glooping or skipping.

Is the 1.0mm tip suitable for left-handed writers?

Yes. Jetstream ink dries virtually on contact, eliminating the ink smear commonly encountered by left-handed writers when moving across freshly written text.

Does this pen bleed through regular paper?

Despite its bold 1.0mm line width, the hybrid formulation adheres crisply to paper fibers without feathering or bleeding through standard notebook and printer sheets.
