    What is the difference between Gel, Roller, and Ballpoint pens?

    In short, liquid ink gives Rollers free-flowing, fluid writing, Gels deliver thick and vibrant lines, and our unique Jetstream pens are known for their incredibly fast and effortless writing. Learn more about their distinct technologies here.

  • Fraud Prevention

    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.

  • Pen Refills

    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.

  • High Altitude Leaks

    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™.

  • Where to Buy

    Where can I find my favorite uni-ball pen?

    Most office supply, superstore, discount, drug, and grocery stores carry many uni-ball pens. If you can’t find your favorite, our Customer Service team will help you — submit a question using the contact form or send us a message on Facebook.

  • Waxy Tip

    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.

  • Removing Ink Stains

    What should I do to remove clothing stains from uni-ball pens?

    Act as swiftly as possible by testing the below stain removal techniques on a hidden part of the garment to ensure the garment does not become discolored. Stain removal techniques vary for the type of ink:

    WATER-BASED INK
    Found in the uni-ball Vision (fashion colors), Vision Exact, Onyx

    WASHABLE GARMENTS
    Step 1 - Soak in skim milk 1/2 hour to 1 hour. Scrub the stain with an old toothbrush or cuticle brush. Rinse with warm water.
    Step 2 - Combine powdered color-safe bleach, such as Clorox 2, with warm water to make a paste the consistency of undissolved sugar. Put this mixture on the stain for 30 minutes to 1 hour. Scrub the stain with an old toothbrush or cuticle brush. Rinse with warm water.
    Step 3 - Repeat Step 1 and Step 2, if needed.
    Step 4 - Launder with a protein-based detergent, such as Era Plus. Make sure the stain is completely removed BEFORE putting the article of clothing in the dryer, as this may set the stain.

    DRY CLEAN ONLY GARMENTS
    Take the item to a commercial dry cleaner who employs a "spotter" and advise him/her that the water-based ink stain contains water-soluble dyes.
