uni-ball VISION Rollerball Bold Dozen

This pack contains twelve uni-ball 70128 rollerball pens with black ink. Each pen uses a bold tip and the manufacturer's Super Ink formulation. The ink is acid-free and designed for archival-quality records. A translucent window lets you monitor the remaining supply.

Suited for high-volume writing and security tasks

The bold line width suits note-taking, record-keeping and document signing where a strong mark is needed. Super Ink bonds with paper fibres to resist water, fading and fraudulent alteration. Buyers who need a finer line or coloured inks should consider other models.

Bold tip with Super Ink fraud protection

The defining specification is the bold rollerball tip combined with acid-free Super Ink that creates a permanent, tamper-evident bond on paper. This combination decides whether the pen meets your writing and security requirements.

Questions about this item

How often will the 1 mm tips on these uni-ball 70128 pens need replacing under normal use?

The pens use a capped rollerball design with strong, long-lasting tips and a Uni-Flow Ink System that delivers consistent ink flow until the cartridge is empty, so the tip itself does not require separate replacement.

What runs out first when writing continuously with a uni-ball 70128 — ink or tip durability?

The translucent ink window lets you monitor the liquid ink level; the ink supply will be exhausted before the tip wears out, at which point the entire pen is replaced.

Does the ink in the uni-ball 70128 bleed or feather after hours of non-stop writing?

The archival-quality, acid-free Super Ink forms an indestructible bond with paper, resisting water, fading and check-washing, so lines stay clean and vivid even during extended sessions.
