Uni-ball Eye Micro Rollerball Pen, 0.5 mm, Waterproof Pigment, Smooth Uni-Flow, Comfortable Barrel, Ideal for Everyday Writing, Blue - Pack of 5

The pen uses pigment-based ink that resists water and handling. Combined with Uni-Flow regulation, the ink dries quickly on paper, helping to minimize smearing during copying, note-taking, or filing.

A 0.5 mm tip offers a fine, legible line that’s great for detailed notes and forms. It provides precision without sacrificing smoothness, making it suitable for everyday writing tasks.

The pack contains five blue Uni-ball UB-150 Eye Micro rollerball pens, all of the same model for consistent performance across daily tasks.

Best on standard writing paper—great for office forms, school notes, notebooks, and everyday writing tasks where clear, legible writing is important.

When not in use, cap the pen to prevent the nib from drying. Store in a cool, dry place away from direct sunlight. Keep the cap securely fitted to maintain ink flow.

Yes. The ink is designed for everyday writing and is non-toxic for general handling. As with any writing instrument, avoid ingestion and keep away from small children who might chew or swallow parts.

This model is designed as a disposable rollerball pen; once the ink runs out, you replace it with another pen rather than refilling the same unit.

If you’re weighing alternatives on Fepy, consider a gel-style pen like the Uni-ball Signo or other 0.5 mm options for different ink feels (gel vs pigment). The pigment Eye Micro offers water resistance and quick set, which is distinct from gel inks that may smear differently on certain papers.

Yes. The regulated ink flow and pigment-based ink help produce clean, consistent lines. The quick-drying, water-resistant ink also helps prevent smearing on forms and copies, making it suitable for signing documents and taking longer notes.

Allow a brief dry time (a couple of seconds) after writing to reduce smearing on copies. Use on standard copier-weight paper and avoid excessive pressing on the nib to keep lines crisp and readable.
