Which pens help prevent document fraud?

Many uni-ball pens, including the uni-ball 207, protect against water, fading and fraud. They contain pigment-based ink that forms an indelible bond in paper and resists criminal check washing. Any uni-ball pen with Super Ink™ is archival quality and perfect for any writing that needs to stay put. 

Which refill works for my pen? Where can I find it?

Check the Refill Guide to see all refillable uni-ball pens. Refills can be purchased at most office supply stores, but if you have any questions please reach out to us using the contact form.

Why do some pens leak in airplane cabins or at high altitude?

Rollerball pens contain thinner, less viscous ink than a ballpoint, typically contained in a closed tube. Fluctuations in pressure while flying cause air to expand inside the ink chamber leading to unexpected inkblots in your briefcase. If you’re unsure your pen is airplane-safe, you can equalize the pressure inside the pen by taking its cap off while holding it tip up. Or, if you want total certainty, look for our airplane-safe pens, such as the Vision Elite™.

I just got a new uni-ball pen. What’s the waxy material on its point?

That is a protective wax that preserves the ink and protects the pen tip. It is an extra step that guarantees your pen writes as intended; simply remove it before writing.
