Is the signature pen a hard pen? Can I use a signature pen in the hard pen calligraphy exam?

Except the writing brush, all pens used for writing or seal cutting are hard pens. Of course, the signature pen belongs to hard pen ~ ~! Of course, it can also be used to test the hard pen ~ ~ secretly telling you: if you are not used to using a pen, I suggest you don't force yourself. Write with ordinary pencils, ballpoint pens, fountain pens and signature pens, and good calligraphy will be at your fingertips ~! It is more pleasing to the judges than what pen art pen I use (I have tried it before, hee hee) ~ ~ ~ I wish you handy and success! thank you
