===Permanent marker===
{{main|Permanent marker}}
Permanent markers are porous pens that can write on surfaces such as glass, plastic, wood, metal, and stone. On most surfaces, the ink is generally resistant to rubbing and water, and can last for many years. However, on certain plastics like [[Teflon]], [[polypropylene]] etc., the marks made by such pens are not permanent and can be erased easily. Depending on the surface and the marker used, the marks can often be removed with either vigorous scrubbing or chemicals such as acetone.
