The Markers we deal in are used for writing on plastics, ceramics, metals, wood, cardboard stone, etc. The mark made by them are permanent or semi-permanent, depending on the surfaces. Their marks can be removed with a little rubbing pressure. Also, the writing made by them has high visibility. We offer the Markers in many brilliant colors, enabling high level of creativity. They're ideal for making loose lines, precise technical illustrations and calligraphic designs. Do insert the caps after the sticks are used, so as to prevent their drying and boost their functionality.
