Can the outline pen be used to write small characters?

In general, it is okay to use the hook pen to write, but it is not suitable for practicing calligraphy. The calligraphy pen can write with a sharp edge, and it is the best pen for practicing calligraphy. If you use the hook pen to practice calligraphy, , it should have no effect, and the characters will not be improved. I suggest that if you feel that your calligraphy pen is too big, you can change to a larger book to practice writing, so that you can get the best of both worlds.
