Uni-ball Zento Flow 0.38 - Agate

The Uni-ball ZENTO is one of those pens that’s easy to reach for again and again. Its minimalist form feels intentional, balanced, and quietly stylish. The specially formulated ZENTO ink writes with noticeably less resistance on the page and holds up well without feathering or bleedthrough.

The Flow model features a refined two-tone silhouette, pairing a softly tinted ABS barrel with a matching anodized aluminum grip inspired by natural stone. Balanced in the hand and smooth on the page, it’s designed for ease and clarity—thanks to ZENTO ink technology that glides with less friction and resists feathering or bleedthrough. A spring-loaded wire clip in the same tone blends into the form, adding a quiet touch of function and elegance.
