Any Parker pen can be used for homework.
For children, you can use Baihui series because it is cheap and easy to write.
When choosing Parker pen, choose the pen with the "F" tip, which is thinner and suitable for making homework paper.
The ink is preferably Parker ink, which is thick and impermeable.
In order to prevent counterfeiting, I had to go to the counter of the big shopping mall to choose Parker pens.
