What kind of pen is Li Libi? Can you elaborate on it?

Just a different name.

It (called gel pen or gel pen) is called gel pen because the things in the pen container are sticky and a little elastic.

As for neutrality, its ink viscosity is higher than that of water-based pen (pen signature pen) and lower than that of oil-based pen (ballpoint pen).

Gel pen is between water and oil.

Incidentally, the so-called "China Oil Pen" on the market now can be considered as a "gel pen" for gel pens and ballpoint pens.

Well, I want to criticize a joint venture stationery company for importing unqualified products into the market! Look at yourself!
