Maintenance of pens:

When writing, some manuscript paper should be placed under the paper to enhance the elasticity of the pen tip and reduce friction. Do not write the pen tip on hard materials such as metal to prevent damage to the pen tip. In daily use, avoid mixing different inks to avoid sedimentation and clogging of the pen.

The pen should be cleaned once every month or so to keep the ink draining smoothly. If carbon ink is used, it should be cleaned more frequently and must be thoroughly cleaned. Finally, there is one more thing you should pay special attention to: Never use boiling water or overheated water to clean the pen, otherwise it will cause damage to the pen. If the pen is not used for a long time, it should be cleaned and stored. And don't use excessive force when writing.
