What kind of pen is this? It's good for signature and good for design. It has a thin and soft head.

It belongs to hard pen. To put it simply, all exhibitions held by China Calligraphers Association should be written with a brush. The exhibition held by China Hard Pen Calligraphy Association can be written with soft pen.

In terms of material, the brush head is made of animal hair. The soft-tip pen is made of plastic and cannot be disassembled.

There is a scientific brush in Japan. The nib is nylon, and there is an ink storage bag in the pen tube, which is also made of special ink.

But this so-called scientific brush can't be compared with the traditional brush.

The elasticity of nylon is constant, and the elasticity of hair is layered.

Nylon has poor water absorption, while animal hair has relatively strong water absorption.

Special ink only ensures that the pen does not coagulate, which does not reflect the effect of five-color ink.
