Uni | Zento Gel Pens - FLOW model

The uni-ball ZENTO Flow is a premium retractable pen designed to deliver an exceptionally smooth, stable writing experience. It uses ZENTO ink technology, developed to create a soft, cushioned feel on paper while maintaining clean, controlled lines with minimal skipping or blotting.

The Flow model stands out within the ZENTO lineup thanks to its anodized aluminum grip section, which adds durability, balance, and a refined tactile feel. A color-matched movable clip enhances both usability and visual cohesion, making the pen suitable for everyday professional use, note-taking, journaling, and long writing sessions.

All ZENTO Flow pens use ZENTO UBR refills, allowing easy replacement while maintaining the same smooth writing performance across the range.
