Rollerball Pen is a type of pen that uses water-based or gel ink that is more fluid than the oil-based ink used in ballpoint pens. This provides a smoother writing experience, similar to using a fountain pen.
A rollerball pen is a type of writing instrument that uses a ballpoint writing mechanism, like a traditional ballpoint pen, but delivers liquid ink (either water-based or gel-based), offering a smoother writing experience.
At the tip of the pen is a tiny ball bearing (usually made of steel or tungsten carbide). As you write, this ball rolls across the paper and:
Picks up ink from the ink reservoir.
Transfers it onto the paper smoothly and evenly.
Rollerball pens use two main types of ink:
Water-based ink:
Flows more easily.
Produces darker and more vivid lines.
Tends to soak into the paper quickly.
Gel-based ink:
Thicker than water-based ink but still smoother than oil-based ink.
Available in a wide range of colors.
Provides bold, vibrant writing.
Smooth writing: Less pressure is needed, reducing hand fatigue.
Vivid color output: Especially with gel inks.
Finer lines: Ideal for precise or small handwriting.
Better on high-quality paper: Works well for journaling, note-taking, and formal writing.
Ink may bleed or feather on cheap/thin paper.
Not water-resistant (especially water-based inks).
Can dry out faster if left uncapped.
Ink runs out faster compared to ballpoint pens.
