Selected for the 2026 Stationery Store Award - Ballpoint Pen Award, uniball ZENTO is praised for its exceptionally smooth writing feel and calm, thoughtful approach to everyday writing.

One pen, three ZENTO ink colors: black, red, and blue. The ZENTO Flow Model 3-Color makes it easy to organize notes, distinguish different subjects, and emphasize important information without carrying multiple pens.

Its newly developed water-based pigment ink provides a soft, cushioned writing experience. The ZENTO ink formulation helps reduce friction between the ball tip and paper while producing clean, controlled lines with less feathering, bleed-through, and show-through.

Positioned between the accessible Standard Model and the premium Signature Model, the Flow Model features an anodized aluminum grip that gives the pen a more substantial and refined feel in hand. Its balanced construction and movable, color-coordinated clip combine everyday practicality with a polished finish.

Each pen contains black, red, and blue refills in the same tip size. Body colors are paired with either 0.38 mm or 0.5 mm tips, so please check the corresponding size when selecting a variant.
