What Is A Mark Pen

The marking pen is a pen that can be written or marked on paper, wood, metal, plastic, and enamel ceramics. The marking pen is divided into an oily marker and a water -based mark. The water -based marking pen can be written on the surface of the smooth object or on the whiteboard. It can be wiped off with a rag (whiteboard pen). The oily mark is not easy to erase.
