Product Description:
Slim type oil-based ballpoint pen with acro ink that features smooth writing.
The shape of the handle is tapered so it is easy to grip and stable to write on.
Smooth writing.
Acro ink used for acroball is made with a viscosity of 1/5 of a standard oil-based ballpoint pen that creates a smooth ink that is close to water based and allows the ball to spin smoothly.
Writes deep.
Acro ink has a low viscosity so the ink supply to the nib. Ink penetrates deep into the paper fibers, resulting in a dark, uneven brush stroke.
