Rollerball Pens

Rollerball pens use a water-based liquid or gel ink, which is delivered through a small ball bearing in the tip. This type of pen combines the smooth ink flow of a fountain pen with the convenience of a ballpoint pen. The liquid ink used in rollerball pens tends to saturate more deeply into paper than oil-based ink from ballpoint pens, resulting in stronger, more vivid lines. However, this can also lead to smudging, especially for left-handed writers, and may require a bit more drying time. Rollerball pens are popular for their smooth writing experience and are available in a wide range of colors.
