Three colours in one pen. The Uni-ball ZENTO features black, red and blue inks with a smooth 0.38mm gel tip, engineered for effortless writing without feathering or friction.
Switch colours using the top buttons—designed for quick recognition and clean aesthetics. The short barrel positions your fingers perfectly for easy transitions, while the smooth click mechanism feels natural with every change.
Built for comfort and control. A wide rubber grip spans the hand-rest area for stable writing during extended use. The slim wire clip sits discreetly on notebooks, planners or pockets without adding bulk.
Ideal for detailed notes, small handwriting, journals and planners. Made in Japan by Mitsubishi Pencil, with a refillable design using standard UBR-ZML-38 refills.
