What is a rollerball pen?

The rollerball pen, a vital tool for everyday writing, is often mistaken for a regular ballpoint pen. However, its unique design and ink system offer a completely different writing experience.

The Core Secret of Rollerball Pens: Water-Based or Gel Ink

The most distinctive feature of rollerball pens lies in the ink they use. Unlike ballpoint pens, which use oily, viscous ink, rollerball pens use either water-based ink (liquid ink) or gel ink (gel ink).

Water-based ink (commonly used in liquid ink rollerball pens): It has high fluidity and wets the ink directly, resulting in vibrant colors and smooth, fountain pen-like handwriting.

Gel ink: A combination of water-based ink and a thickening agent, it combines the vibrant colors of water-based ink with the quick-drying properties of ballpoint ink and is less prone to feathering.

Because of the low viscosity of these inks, rollerball pens don't require the same firm pressure as ballpoint pens. Simply glide the tip across the paper, and the ink flows quickly and evenly, delivering an exceptionally smooth writing experience.

Differences from Ballpoint Pens and Fountain Pens

The best way to understand the characteristics of rollerball pens is to compare them to other common writing instruments:

Rollerball pens offer a perfect blend of ballpoint pen technology and the writing feel of fountain pens. They use the ball of a ballpoint pen as the ink dispenser, but mimic the rich, smooth feel of a fountain pen by using water-based ink.
