Mannenmōhitsu Sen Series

As a brush pen manufacturer, with the desire to pass on the culture of "writing" to future generations,
we have developed a sustainable, unprecedented brush tip called "Sen" as an alternative to animal hair.

Skilled brush makers meticulously craft each brush using a special polyester hair material that offers the same writing experience as weasel hair.
It reproduces the smooth writing feel and appropriate elasticity unique to animal hair, allowing for beautiful expression of brush strokes. In addition, the tip is highly responsive and well-formed, making it a satisfying choice even for those familiar with brush writing. The tip boasts high durability, allowing you to enjoy its excellent writing quality for a long time.
