Uni-Ball Zento Flow Model Gel Pen 0.38mm, 0.5mm

Refined, minimal, and engineered for effortless writing, the Uni-ball Zento Flow in Birch White and Anthurium Pink brings together modern Japanese design and high-performance ink technology.

At the core is Uni-ball’s smooth-flow gel system, delivering a consistent, skip-free line with a precise tip—ideal for clean handwriting, detailed notes, and planners where accuracy matters. The ink lays down evenly with a soft, controlled glide, reducing hand fatigue during long writing sessions.

The barrel features a dual-texture construction: a subtly matte upper body paired with a new anodized aluminum grip section, giving you both comfort and control. The ergonomic taper and balanced weight distribution make the pen feel stable in hand without being bulky, striking that sweet spot between lightweight and premium.

Design-wise, these pens lean into understated elegance. Birch White offers a crisp, neutral tone inspired by natural wood, perfect for a calm, minimalist setup. Anthurium Pink introduces a muted blush accent—soft and sophisticated rather than overly bright. Both are complemented by a sleek metal clip with a circular accent detail, adding durability and a quiet, polished finish.
