Uni-ball Zento Fine Rollerball Pen, 0.7 mm, Water-Based, Ultra-Smooth, Comfortable Grip, Ideal for Everyday Writing - Coastal Barrel / Blue Ink

Fine line: 0.7 mm; Ink: water-based for clean, consistent output; Writing feel: ultra-smooth with a low-friction system; Grip: comfortable ergonomic barrel; Ideal use: everyday notes, letters, and planning.

Water-based ink typically delivers clean, crisp lines with smooth flow and quick drying on proper paper. It can feel more fluid than oil-based inks, but may require a gentler writing pressure to prevent smears on certain papers.

Perfect for everyday writing such as personal notes, letters, to-do lists, planning pages, and quick jotting where neat, readable lines are desired.

The pen uses a low-friction writing system that reduces resistance, allowing for faster, smoother strokes and more consistent ink flow across the page.

It features a coastal-colored barrel with an ergonomic, comfortable grip designed to support steady control and reduce hand fatigue during longer writing sessions.

Cap the pen when not in use to prevent the ink from drying out. Use on quality writing paper, avoid pressing hard, and store upright or with the cap on to maintain ink flow and tip integrity.

Yes. The water-based ink is non-toxic and suitable for general writing tasks in school, home, or office environments. As with any writing instrument, keep out of reach of small children who might put it in their mouths.

The Coastal model differs mainly by barrel color and ink color while sharing the same 0.7 mm fine-rollerball design and overall writing feel.

Great for students taking notes, professionals drafting quick memos, planners and organizers, and anyone who prefers a smooth, readable 0.7 mm line for everyday writing tasks.

Use quality paper to prevent feathering, avoid excessive pressure to maintain consistent ink output, keep the cap on when not in use, and replace the pen or refill if the ink flow becomes inconsistent.
