The Zento Ink Formula

Low-Friction Ink Flow

A newly developed ink reduces writing resistance, delivering a smoother, more effortless glide.

Cushioned Writing Feel

A POA surfactant within the ink creates a lubricating layer, softening contact between tip and paper.

Controlled Ink Dispersion

Attracting particles bind the ink together, minimizing bleed-through and maintaining clean, defined lines.

Smudge-Resistant Performance

The ink dries cleanly on the page, helping reduce smudging for a more reliable writing experience.
