Uni-ball Eye Broad Rollerball, 1.0 mm, Waterproof Pigment, Smooth Uni-Flow, Ideal for Emphasis & Markups - Red

Key specs include a 1.0 mm tip for thick lines, water-resistant pigment ink, Uni-Flow control for even ink delivery, fast-drying ink, and a comfortable round barrel designed for everyday use such as grading and visible corrections.

Ideal for emphasis, headings, markup, and general note-taking where you want bold, legible text. It’s also handy for grading, marking corrections, and making important notes stand out in textbooks or notebooks.

Uni-Flow control regulates the ink flow to prevent skips or blobs, delivering smooth, even lines consistently across pages.

A 1.0 mm line delivers bolder, more pronounced strokes ideal for headings and emphasis, while smaller tip variants (like 0.7 mm) produce finer lines for subtler notes.

It works well on standard notebook and printer paper for school, office, or home use. It’s designed for everyday writing tasks that require bold, legible marks like headers, notes, and corrections.

Hold the pen with a relaxed grip at a comfortable angle (roughly 45 degrees), apply even, light pressure, and use long, steady strokes. Avoid pressing too hard and let the ink flow smoothly for uniform lines.

Let the ink dry briefly before crossing or stacking pages, cap the pen when not in use, and avoid rubbing the freshly written area. The fast-drying pigment helps reduce smearing during normal handling.

The ink is designed for regular writing use and is formulated to be appropriate for typical classroom and office settings. Always follow your local safety guidelines and school or workplace policies.

Yes, the product can be returned under Fepy’s standard return policy if it doesn’t meet your expectations. Be sure to review the policy terms applicable at the time of purchase.
