Mitsubishi Pencil Uni-ball ZENTO Standard 0.38 – Black Ink Ballpoint Pen (Set of 4)

The Mitsubishi Pencil Uni-ball ZENTO Standard 0.38 is a finely tuned Japanese ballpoint pen created for those who value precision, calm writing, and mindful moments. This set of four pens features soft, expressive shaft colors—Cloud, Adobe, Lavender, and Sea—so you can choose the one that best fits your time, place, mood, and state of mind.

Powered by newly developed ZENTO ink, this pen delivers a stress-free, soft writing feel with crisp, beautiful lines. A cushioning ingredient (POA surfactant / polyoxyalkylene) forms a gentle buffer between the ball tip and paper, reducing friction by approximately 40% compared to previous Uni-ball products. The result is smoother strokes, less resistance, and reduced hand fatigue—especially noticeable with the extra-fine 0.38 mm tip, ideal for detailed notes and neat handwriting.

ZENTO ink also helps reduce bleeding and smudging by attracting ink particles together, keeping lines controlled and clean. A long rubber grip ensures steady handling during extended writing sessions, while the barrel made from recycled materials reflects Mitsubishi Pencil’s commitment to sustainability.

Perfect for journaling, studying, planning, or quiet reflection, Uni-ball ZENTO transforms everyday writing into a more comfortable and intentional experience.
