In modern times, you can get varieties of pens in the market which suits best to your need. In this pen world rollerball pen has also gained much of popularity. Rollerball pens are writing instruments which use ball point writing mechanisms with water-based liquid or gelled ink, as opposed to the oil-based viscous inks found in ballpoint pens. The characteristics of these less viscous inks, which tend to saturate more deeply and more widely into paper than other types of ink, give rollerball pens their distinctive writing qualities. The rollerball pen was initially designed to combine the convenience of a ballpoint pen with the smooth "wet ink" effect of a fountain pen. Gels also allow for the use of heavier pigments with metallic or glitter effects, or opaque pastel pigments that be seen on dark surface.

Rollerball Pen Pros
- In order to write it cleanly or spruce up your note book, you just need to apply less pressure. This permits holding the pen with less stress on the hand, saving energy and improving comfort.
- The ink usually has a greater range of colors due to the wider choice of suitable water-soluble dyes and/or to the use of pigments.
- They usually tend to write more boldly and clearly than ballpoint pens do.

Rollerball Pen Cons
- A rollerball tip is more likely to jam with correction fluid when writing over while it is not completely dry. This often renders the pen useless.
- Uncapped rollerball pens are more likely to leak ink when, for example, placed into a shirt pocket, but this is easily avoided by recapping the pen.
- A disadvantage of gel ink is that its greater viscosity increases the likelihood of intermittent (as opposed to consistent) inking of the ball, producing "skipping" where the flow of ink randomly ceases. The amount of skipping varies widely with the pen. Conversely, liquid-ink rollerball flow extremely consistently, and skip less than ballpoints do.
- Water-based rollerball ink is more liable to smudge than a ballpoint pen's oil-based ink because water-based ink dries more slowly. Also if one writes in a notebook, closing it before the ink dries can stain the opposing page. Gel ink dries much more rapidly than liquid-ink, making it much more, but not completely, resistant to smudging.
-Rollerball pen with liquid-ink much more frequently "bleeds" through the paper. Liquid ink is more readily absorbed into the paper due to its lower viscosity. Though the bleed-through effect of a gel-ink rollerball is greater than that of a ballpoint, it is usually not too significant.

Thus, availability of rollerball pen is not a big task from the market. Now-a-days black rollerball pen is seen much in demand in hands of people.
