There are two main types:
1. Plug-in gel pen
The cap-type gel pens come with a cap. The cap can change various shapes to make the pen of the pen look more beautiful; more importantly, it can protect the pen.
2. Press the 中 type gel pen
Pressing the 中-type gel pen is quite different from the cap-type neutral. Pressing the 中-type gel pen through the continuous fitting of the pen tail, pressing the back part down, clasping the convex position of the pen body makes the pen tip protrude, and there is a pen at the pen tip. The spring assists the bombing, which is more convenient and quicker during use, and can effectively prevent the pen tip from being poked.
