Uni-Ball ZENTO 3 Color Gel Multi Pen | Flow Model

Description

The Uni-Ball ZENTO Flow Model brings ZENTO's smooth, easy-flowing writing experience to a convenient three-color pen. With black, red, and blue ink in a single slim barrel, it's easy to switch colors when taking notes, organizing information, or adding color-coded details to your planner.

The Flow Model is designed with an aluminum grip that adds a little weight and helps create a stable writing feel. The grip features a combination of blasted and hairline finishes, giving the metal a subtle variation in texture. A movable color clip corresponds to the selected ink, while the coordinated metal accents add a clean, understated look.

Choose between a fine 0.38 mm point or a slightly broader 0.5 mm point. The 0.38 mm version is available in Navy and Light Green, while the 0.5 mm version comes in B Burgundy and Beige.

All three colors use ZENTO's water-based ink, developed for a soft, smooth writing experience with less of the scratchy sensation associated with some finer-point pens. The three-color format makes it particularly useful when you want to switch between colors without changing pens.
