I made it because I wanted a pen that could complete the pen insertion to some extent with the strength of the pen pressure without changing the thickness.
I aimed for a pen that does not break the line even if the force is relaxed, and the entry does not become thinner. Probably for people with weak pen pressure.
太さを変えずに筆圧の強弱である程度ペン入れが完結するペンが欲しくてつくりました。
力を抜いても線が途切れない、入りが細くならないペンを目指しました。恐らく筆圧弱めの人向けです。
Have fun!
お楽しみください!
