Product Information

Full details

The Uni-Ball UB-157E Liquid Ink Rollerball Pen is an ideal choice for office professionals, students, and artists who require a reliable writing instrument for daily tasks and long-term documentation. Featuring high-quality Super Ink technology, it provides a smooth, skip-free writing experience that keeps your work permanent and secure against environmental factors. While the 0.5mm line width is perfect for detail, users should note that the liquid ink formula requires a moment to dry on non-porous surfaces to prevent smudging.

Extended Product Information

FAQs

Are these pens suitable for left-handed writers?

Yes, the unique ink flow system is designed to minimize friction and provide a smooth experience for both left and right-handed users.

Is the ink actually waterproof?

The Uni-Ball Super Ink is formulated to be water-resistant and fade-resistant once it has fully dried on the paper, making it highly durable for archiving.

Can these pens be refilled?

No, the UB-157E is a disposable liquid ink rollerball pen designed for convenience and cannot be refilled.

What is the tip size compared to the line width?

The pen features a 0.7mm tip size, which produces a 0.5mm consistent line width.

Can I use these pens on checks or legal documents?

Yes, because the ink is tamper-proof and resistant to water and light, it is an excellent choice for signing checks and formal legal documents.

Troubleshooting

Pen is skipping during writing

Check the tip for paper fibers or lint build-up. Gently wipe the tip with a soft cloth to restore ink flow.

Ink is smearing on the page

Ensure you are using appropriate paper weight. If you are left-handed, try adjusting the angle of the pen to reduce contact with the fresh ink line.

Pen feels dry after storage

Shake the pen gently to encourage ink flow to the tip, or scribble firmly on a scrap piece of paper for a few seconds to prime the internal system.

Pros and Cons

Pros

  • Permanent, water-resistant ink ideal for archiving documents
  • Extremely smooth writing experience with no skipping
  • Visible ink supply prevents unexpected run-outs
  • Excellent for both right and left-handed users
  • Tamper-proof ink formula provides added security

Cons

  • Liquid ink may bleed through very thin paper
  • Ink takes slightly longer to dry than standard ballpoint pens
  • Cap must be replaced securely to prevent drying out
  • Not refillable once the ink supply is exhausted

Setup, Compatibility & Care

No complex setup is required; the pens are ready for use immediately upon removal from the packaging. To maintain optimal performance:

  1. Cap Management: Always ensure the cap is pressed firmly onto the pen after use. The cap-off system is designed to keep the ink flow active, but leaving it off for extended periods can cause the tip to dry.
  2. Storage: Store pens horizontally whenever possible to ensure an even distribution of ink within the reservoir.
  3. Surface Compatibility: This pen performs best on standard to high-quality stationery. Avoid writing on glossy or coated surfaces, as liquid ink may not absorb properly and will remain susceptible to smearing.
  4. Temperature: Keep pens away from extreme heat or freezing temperatures to preserve the chemical integrity of the Super Ink formula.
