Uni-ball Eye Micro Rollerball Pens, 0.5 mm, Waterproof Pigment, Smooth Uni-Flow, Comfortable Barrel, Ideal for Everyday Writing, Blue & Black – Pack of 2

Tip size: 0.5 mm. Ink: pigment-based, water-resistant with quick-drying properties. Flow: regulated by Uni-Flow for consistent lines. Design: comfortable rounded barrel and dual-color body for easy color identification. Pack: 2 pens in blue and black.

Uni-Flow is designed to provide a steady, controlled ink flow from start to finish, reducing skipped lines and creating uniform strokes across the page.

The pigment ink is water-resistant, helping to resist smudging after writing. It is not fully waterproof if exposed to immersion or heavy wet exposure.

They perform well on notebooks, planners, and standard copier or office papers. The quick-drying pigment helps keep margins clean on typical paper stocks.

Dual colors make it easy to distinguish sections, filings, or categories at a glance, aiding organization and quick color-coding in your notes.

Remove the cap before writing, then cap the pen when not in use to prevent ink from drying out. Store at moderate room temperature and avoid extreme heat or cold.

These Eye Micro rollerball pens are designed as convenient, disposable writing instruments rather than refillable pens.

Yes. The ink is pigment-based and designed for everyday writing. They are suitable for office, school, and home use. As with any writing instrument, avoid ingestion and keep out of reach of small children.

A 2‑pen pack provides color options for different tasks (blue for forms, black for notes) and ensures you have a spare or can share with a colleague, offering better value for daily use.

First, ensure the cap is securely in place when not writing. Use on clean, dry paper and avoid writing on damp surfaces. If skipping occurs, try writing a few quick strokes to prime the ink and avoid excessive pressure that can cause smearing.
