The Uni-ball ZENTO Gel Pen 0.5mm is a next-generation retractable gel pen designed to deliver a smooth, stress-free writing experience. Engineered with Uni’s newly developed water-based ZENTO pigment ink, it features low-friction technology (using POA surfactants) that acts as a cushion between the pen tip and paper for fluid, effortless writing.

Its crisp, quick-drying ink resists smudging, feathering, and bleed-through, while offering high water and light resistance. The pen body highlights a sleek, minimalist aesthetic with an extended soft-touch grip for flexible hand placement and a durable, spring-loaded wire clip that opens wide to secure easily onto notebooks, pockets, or documents.
