Slimline oil-based pen with Acro ink for smooth writing.
The grip has a tapered tip for easy holding and stable writing.
The Acroball uses Acro Ink, which is 1/5 the viscosity of a normal oil-based ballpoint pen, and the ink is silky smooth, similar to water-based inks.
Acro Ink's low viscosity ensures an ample supply of ink to the pen tip. The ink penetrates deep into the paper fibers, making the writing stroke even and thick.
