There are three types of pens.
A touch pen (passive pen) can be provided at a low price, but the pen tip is thick and it is easy to misdetect the palm, so it is not easy to use and the drawing performance is not good. On the other hand, battery-powered pens (active pens) have high drawing performance, but they are relatively expensive and require a battery, so they tend to be heavy and thick and have poor balance in the center of gravity. Furthermore, these pens cannot be stored in the body of a tablet or smartphone and carried around.
Raisontech pens can provide a totally balanced product that solves that shortcoming.
