Writing smoothly with “Acro Ink”'s slim, oil-based ballpoint pen.
The tip of the body is thick for easy grip. The center of gravity is in the front, and the writing is stable.
[Can write smoothly]
< span style="font-size:14px;">The viscosity of the acro ink used for the acro ball is 1/5 of that of a general oil-based ballpoint pen, making it a smooth ink close to water-based, and the ball spins smoothly.
[Can write very deep]
Acro ink is less viscous, so the nib has a good supply of ink. As the ink penetrates deep into the paper fibers, the handwriting becomes even and deep.
