FAQs

Is the ink archival safe?

Yes, the uni Super Ink is fade-resistant and designed to last for years, making it suitable for archival purposes.

Can I use this pen for check signing?

Absolutely. The ink is tamper-proof and water-resistant, which is ideal for securing financial documents.

Are these pens refillable?

The Uni-Ball Gel Impact series is generally designed as a disposable unit.

Will this ink smear if it gets wet?

No, the ink is formulated to be water-resistant once it has dried on the page.

How do I know when the pen is running out of ink?

The barrel includes a transparent viewing window that allows you to see the remaining ink levels directly.

Troubleshooting

Pen is skipping or writing dry

Scribble in circular motions on a scrap piece of paper to jumpstart the ink flow, or check if the ink window shows an empty reservoir.

Ink smearing on the page

The Gel Impact utilizes a high-flow ink; try adjusting your writing speed or using a paper type that is less absorbent to give the ink time to set.

Ink bleeding through to the other side of the paper

Switch to a higher-gsm (heavier weight) paper or use a backing sheet while writing.

Pros and Cons

Pros

  • Ultra-smooth ink flow requiring minimal pressure
  • Superior ink security against water and tampering
  • Bold line width stands out on any paper type
  • Comfortable grip suitable for long writing sessions

Cons

  • Ink takes longer to dry than standard ballpoints
  • Not recommended for thin or low-quality paper due to potential bleed-through
  • Bold tip may feel too heavy for users who prefer fine-point writing

Setup, Compatibility & Care

This pen requires no special setup; it is ready to use immediately upon removal of the cap. To maintain performance, ensure the cap is securely snapped back onto the pen after every use to prevent the gel ink from drying out.

Compatibility-wise, this pen works best on standard-weight or heavy-weight paper. If you are writing on very thin paper (such as standard newsprint), test the ink on a corner first to ensure it does not bleed through. To care for your pen, store it in a cool, dry place and avoid exposing the barrel to extreme temperatures, which can affect the viscosity of the gel ink.
