What if the signature pen doesn't go into the water?

Generally, poor drainage means that the ink in the signature pen is blocked due to long-term non-use or infrequent use. The general method is to bake it on the heating for one night, blow the refill or pen evenly with a hair dryer for about ten minutes, or bake it around an open flame for a few minutes. Heat the pen and throw it again, and it will be basically smooth! ~
