Mitsubishi Uni-ball ZENTO Gel Pen — Standard 0.5mm

The Mitsubishi Uni-ball Zento Ballpoint Pen transforms everyday writing into something quietly satisfying. With its newly developed water-based ZENTO ink, it glides across the page in soft, expressive strokes – no drag, no fuss, just effortless flow. Designed with a long, cushioned grip and a recycled barrel, it feels as good for the planet as it does in your hand. Each colour invites you to write in tune with your moment – whether it’s time, place, or mood that guides your choice. A pen for slowing down, collecting thoughts, and putting them gently into words.

Why it is classed as a gel pen

Although the ZENTO’s ink has sparked some discussion, its behaviour aligns closely with gel technology. The ink is water-based, smooth, saturated, and designed to lay down cleanly while drying at a practical speed—all familiar traits of modern gel pens. In day-to-day use it performs like a gel: consistent flow, rich colour, and reduced bleedthrough compared with standard liquid rollerballs. For these reasons, it sits comfortably in the gel-pen category while still carrying Uni-ball’s own distinctive approach to ink formulation.
