Uni-ball Zento Flow 0.38 mm Gel Pen Agate

The Uni-ball Zento Flow is part of Uni’s new Zento line, developed to deliver a smooth, stable, and comfortable writing experience through a balanced combination of advanced ink technology and refined design. This collection is designed to support precise and natural everyday writing.

The Flow version stands out for its solid and refined construction, featuring a metal grip that provides excellent balance and control. The carefully calibrated weight enhances stability and comfort, even during extended writing sessions.

This model features a 0.38 mm tip, ideal for those who prefer a fine, precise, and detailed line. The 0.38 mm size allows for neat, controlled writing, particularly suited to compact notes and high-density text.

The pen uses a water-based gel ink formulated to reduce friction on the page and ensure a consistent ink flow. The result is smooth, even writing with good drying speed, helping to minimize smudging.

The Agate version is defined by a deep and refined tone, inspired by the natural elegance of the stone from which it takes its name. Subtle and contemporary, this color adds character without overpowering the design.

A functional detail is the spring-loaded clip, designed to attach easily to pockets, notebooks, and planners while protecting the clip structure over time.

The Uni-ball Zento Flow 0.38 mm Gel Pen Agate is designed for those seeking an elegant, precise, and comfortable gel pen, combining modern aesthetics with reliable writing performance.

The pen is refillable with the Uni-ball Zento UBR-Z-38 refill, designed to preserve the same smooth and consistent writing performance over time.
