Uni-ball Zento Fine Rollerball, 0.7 mm, Water-Based, Ultra-Smooth, Comfortable Grip, Ideal for Everyday Writing, Green – Pack of 12

Key specs: 0.7 mm green tip for readable lines, ultra-smooth low-friction writing, water-based ink for tidy output, a comfortable barrel grip for relaxed control, and a 12-pack configuration for frequent writers.

The 0.7 mm green line creates a distinct, easy-to-scan contrast that stands out in notes, planners, and forms, making headings, highlights, and daily reminders visually easy to locate.

The pen uses water-based ink that delivers consistent lines with minimal resistance, resulting in a smooth, reliable writing feel across many paper types.

Yes. Uni-ball Zento pens typically use replaceable cartridges. Look for compatible Zento cartridges to maintain the same smooth, 0.7 mm writing experience.

It performs well on standard notebook and printer papers. For very glossy or highly coated surfaces, you may see slower ink response or slight feathering.

Cap the pen when not in use to prevent ink drying, write with a relaxed grip and steady pace for clean lines, and store in a cool, dry place away from direct heat.

The ink is water-based and designed for everyday writing. As with any writing instrument, avoid ingestion and contact with eyes; keep out of reach of young children and follow general safety guidelines.

A 12-pack offers ongoing availability for frequent use, supports consistent color-coding across multiple projects, and can reduce per-item cost compared with buying individual pens.

Ideal for planners, checklists, note-taking, form filling, and color-coded headings. The green 0.7 mm line helps sections stand out and keeps daily notes organized.

Store capped and upright when possible to avoid ink drying at the nib. If you notice slower ink flow, gently rotate the pen to re-prime the tip and ensure the cap is securely closed after use.
