Selected for the 2026 Stationery Store Award - Ballpoint Pen Award, uniball ZENTO is praised for its exceptionally smooth writing feel and calm, thoughtful approach to everyday writing.

Its anodized aluminum grip and balanced weight give it a more substantial, refined feel in hand, while the newly developed ink helps produce clean, crisp lines with excellent water and light resistance.
