Signo Ink
Uni’s well-loved Signo ink is a water-based pigment ink with vivid color and good resistance to water and fading. The ink is developed to improve smoothness while keeping the vivid color, crisp fine lines, and clean writing feel that the Signo series is known for.

Edge-less Tip Design
The tip is specially shaped with rounded edges where it touches the paper, helping reduce friction and making the pen feel smoother during writing.
