Experience the evolution of smooth. The Uni-ball One P "Zento" (from the Japanese word for meditation or calm) features a unique, water-based pigment ink designed for a "cushioned" writing feel. This model combines the adorable, pocket-sized "P" body with a soft, marble-toned aesthetic and high-performance engineering.
The "Zento" Ink Experience
Unlike standard gel pens, the Zento ink formula is designed to reduce the "scratchy" feel of ultra-fine tips. It uses a specialized surfactant that allows the pen to glide across the paper with a buttery, weighted sensation—turning every note into a moment of focus.
Product Highlights
Compact "Pocket" Body: A shorter, wider barrel designed to fit naturally in the palm of your hand and clip perfectly into A6 planners or small pouches.
Low Center of Gravity: Features a built-in metal stabilizer at the tip to provide a steady, "grounded" feel that prevents tip-wobble and hand fatigue.
Superior Contrast: Despite its soft feel, the ink remains incredibly bold. The pigment stays on top of the paper fibers for a crisp, high-contrast line that is easy to read and archive.
Sophisticated Aesthetic: The Irogami series offers a matte, stone-like finish that is both professional and calming.
