Shūgetsu (Shūhitsudō)

Name writing on calligraphy paper for school children. The stiff bristles make this small brush easy to use, even for children just starting their lessons.
The problem with children is that they are unable to fine-tune their writing pressure, so they often damage the tip of a fine brush with too much pressure.
The key is to choose a small brush that is affordable and easy to replace, rather than an expensive one.
