A new kind of ballpoint pen that writes as lightly as air.

The line width changes according to how you hold the pen and the pressure you apply, allowing you to write characters with clear definition, such as stops, hooks, and sweeps, as well as expressive lines with nuanced intonation.

It controls the ink flow according to the pressure applied, resulting in a writing experience as light as air.

This pen features a newly developed tip that moves up and down in response to writing pressure, optimally controlling ink flow. As a result, it allows for clear writing without applying much pressure, providing a comfortable writing experience with minimal skipping.

Soft cover with minimal friction against paper

The soft cover that surrounds the pen tip reduces friction with the paper, allowing for smooth, snag-free writing.

Line width varies depending on writing style and pressure.

This ballpoint pen allows you to create characters with nuances like stops, hooks, and sweeps, and a sense of depth that were previously impossible to achieve with conventional ballpoint pens. It's the world's first ballpoint pen that allows you to change the line width depending on how you write and the pressure you apply. Writing upright or with light pressure results in thinner lines. Writing at an angle or with strong pressure results in thicker lines.

Soft cover that adapts to each individual's writing style

Because the soft cover is made of resin, it conforms to each individual's writing style the more you use it, more so than traditional metal tips. It accommodates various grip styles, whether you're left-handed or right-handed.

A styling inspired by fountain pens, designed to express the power of drawing lines.

Composed of soft curves, its smooth shape with no steps all the way to the tip is designed to highlight its characteristic "expressiveness of lines." Inspired by an evolved version of the fountain pen, its distinctive styling is modeled after the nib of a fountain pen.
