The liquid in the gel pen includes pen water, oily liquid in the refill of a ballpoint pen, and an organic solvent, so it is called a gel pen (or Roller ballpen).

The viscosity of the organic solvent in the gel pen refill is lower than that of oil-based pen ink and denser than water-based pen ink. When writing, the ink passes through the pen tip and turns from semi-solid to liquid ink. The biggest advantage of gel pen ink is that every drop of ink is used on the nib and will not evaporate or leak water, so it can provide a silky smooth writing feeling, and the ink flow is smooth and stable.

Gel pens originated in Japan. In 1988, Japanese Pentel Co., Ltd. successfully developed a product called HYBRID, and the transformation of gel pens was announced. Because gel pens have the advantages of both fountain pens and ballpoint pens, they have a comfortable writing feel, so they are very popular with people and are expected to develop rapidly. Not only have they squeezed out fountain pens from the market, they are also likely to replace ballpoint pens.
