Is this pen heavy or light? What is the reason?

It is nonsense to say that you have never really touched the pen or rarely used it to write. \ r \ nA A pen that is too heavy will be very tiring to write. Although it feels good in your hand, it is not practical at all. \ r \ Many high-end pens are made of various resins or some high-grade plastics, what's more, the plastic material is relatively light, and it won't be too tiring to write. If it can be stored for a long time, plastic will explode into metal. Because plastics are hard to age, but metals are easy to corrode \ r \ nTherefore, it is suggested that you choose some advanced plastics as pen holder materials, such as celluloid, which is very good \ r \ nPlease use it.
