Product Information
Full details
The Uni-Ball Air Micro is designed for professionals and students who appreciate the expressive ink flow of a fountain pen but require the convenience and reliability of a standard rollerball. Its primary benefit is a friction-free writing experience that adapts to your pressure, producing variable line widths; however, users should note that the ink takes a few moments to dry on non-porous paper surfaces compared to traditional ballpoints.

FAQs
Can I use these pens for legal documents?
Yes. The Uni-Ball Super Ink is fade-resistant, water-resistant, and tamper-proof, making it excellent for important archival documents.
Does the line width change automatically?
It changes based on the pressure you apply. Light pressure produces a fine 0.25mm line, while firmer pressure expands it to 0.45mm.
Are these pens refillable?
No, these are disposable rollerball pens designed to be replaced once the ink supply is exhausted.
Do these pens bleed through standard notebook paper?
On most standard notebook paper, the ink performs well, but on very thin paper, you may notice some shadowing.
What is the primary difference between the Air Micro and a standard ballpoint?
The Air Micro uses a pressure-sensitive nib that mimics the smooth flow of a fountain pen, whereas standard ballpoints use a rotating ball mechanism that provides a more consistent, static line width.
Troubleshooting
Pen skips during writing
Ensure the cap was fully closed during storage. If it remains dry, draw a series of loops on a piece of scrap paper to re-prime the flow.
Ink smearing
Reduce pressure while writing or use a higher-quality, more absorbent paper to allow the ink to settle faster.
Pros and Cons
Pros
- Smooth, fountain-pen-like writing experience
- Pressure-sensitive lines allow for creative handwriting
- Archival-quality ink prevents tampering and fading
- Ergonomic feel reduces hand fatigue during long writing sessions
Cons
- Slower drying time than standard ballpoint pens
- Ink may bleed slightly on extremely thin or low-quality paper
- Caps must be replaced firmly to prevent ink evaporation
Setup, Compatibility & Care
To ensure peak performance, store the pens with the cap securely snapped on when not in use to maintain ink viscosity. When using the pens on specialized paper, test on a small area first to ensure the ink absorption meets your standards. Avoid using these pens on glossy photo paper or coated surfaces, as the specialized liquid ink requires porous material to bond correctly. Keep pens stored horizontally in a drawer to ensure the ink remains evenly distributed in the nib.
