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.

Three ZENTO ink colors—black, red, and blue—are housed inside one refined Signature Model. A rotating selector allows you to switch between the three colors, making it easy to organize notes, mark corrections, and separate ideas without changing pens.

ZENTO’s newly developed water-based pigment ink provides a soft, low-friction writing experience. Its cushioning ingredient helps reduce friction between the ball tip and paper, while the pigment ink helps maintain clean lines with less feathering, bleed-through, and show-through.

As the premium model in the three-color lineup, the Signature features a magnetic cap that closes with a satisfying click. The cap can be posted on the back while writing, and the three ink colors can still be selected by rotating the pen’s textured selector section.

Silver is supplied with 0.38 mm black, red, and blue refills, while Metallic Black is supplied with the same three ink colors in 0.5 mm.
