Product Information

Full details

The Uni-Ball Signo Gel Grip Rollerball Pen is designed for professionals, students, and writers who require reliable, high-performance ink for everyday tasks. Its standout benefit is the ultra-smooth, archival-quality gel ink that resists fading, water, and tampering, ensuring your documents remain secure and legible. While it offers excellent writing consistency, users should note that the 0.7mm tip may require a moment to dry on non-porous surfaces to prevent smudging.

Extended Product Information

FAQs

Is the ink waterproof?

Yes, the Signo gel ink is formulated to be water-resistant and fade-resistant once dry.

Does the ink bleed through thin notebook paper?

On standard notebook paper, the ink is generally well-contained and does not bleed through, though it may show slightly on very thin or low-quality newsprint.

Can I replace the ink cartridge?

No, the Uni-Ball Signo Gel Grip is a disposable rollerball pen designed to be used until the ink supply is exhausted.

What is the line width of this pen?

The 0.7mm tip produces a clean, precise 0.4mm line width.

Is this pen considered archival quality?

Yes, because the ink is tamper-proof, fade-resistant, and water-resistant, it is suitable for documents that need to be preserved for a long time.

Troubleshooting

Pen is skipping or writing faintly

Check if the ball tip has dried ink; scribble rapidly on a scrap piece of paper to restore flow or gently warm the tip with your fingers.

Ink smearing on the page

Ensure you are using paper that absorbs ink well; avoid glossy surfaces and give the ink a few seconds to set if you are left-handed.

Pros and Cons

Pros

  • Smooth and consistent ink flow
  • Archival properties protect against document tampering
  • Ergonomic design minimizes hand strain
  • Easy-to-read ink levels through the barrel window

Cons

  • Ink can smudge on glossy or non-porous paper if not given time to dry
  • Not refillable once the cartridge is empty
  • Cap must be manually removed and replaced

Setup, Compatibility & Care

This pen requires no setup; simply remove the cap and begin writing. To maintain optimal ink flow and longevity, store the pen with the cap firmly snapped in place whenever it is not in use, as this prevents the gel ink from drying out at the tip. Store the pens horizontally or tip-down to ensure the ink remains at the nib for an immediate start. Avoid leaving the pen in extreme temperatures, such as a hot car, as this can affect the viscosity of the gel ink and lead to leaking or irregular flow. The pens are compatible with most standard paper stocks and are best suited for use on matte or semi-matte surfaces for the best drying results.
