Uni-ball Zento Flow 0.38 mm Gel Pen Birch White

The Uni-ball Zento Flow is part of Uni’s new Zento line, developed to deliver a smooth, stable, and comfortable writing experience through the combination of advanced ink technology and contemporary design. A collection created to make everyday writing feel natural and effortless.

The Flow version stands out for its refined and solid construction, featuring a metal grip that improves balance and provides greater control while writing. The carefully calibrated weight ensures 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 and controlled writing, making it perfect for compact notes, studying, planning, and high-density text.

The pen uses a water-based gel ink formulated to reduce friction on the page while maintaining a smooth and consistent ink flow. The result is soft, controlled writing with good drying speed, helping to minimise smudging and imperfections.

The Birch White finish is inspired by the light and natural tones of birch wood, featuring a refined warm white shade with a minimalist and elegant character. A bright and contemporary colour, perfect for those who appreciate understated yet sophisticated writing instruments.

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

The Uni-ball Zento Flow 0.38 mm Birch White is designed for those seeking an elegant, precise, and enjoyable gel pen, combining comfort, modern design, and 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.
