Have you studied the core materials?

Yes, but it is not realistic at present.

The core material is hot melted with electricity, and the writing material is solid at room temperature.

What I consider is to electrically heat the metal at the top, and then accurately heat the surface of the carbonized paper, but this has a lower limit for the paper.

Have all the sign pens been charged now??

Because refill ink and refill plastic are used too much every year, the main focus is environmental protection, and this is just a concept, hey hey
