Permanent and Specialty Markers
Permanent markers are porous pens that can write on surfaces such as plastic, wood, metal, and stone. The ink is generally resistant to rubbing and water, and can last for many years. A non-permanent marker (also called a whiteboard marker or dry erasable marker), uses an erasable ink—an ink that adheres to the writing surface without binding or being absorbed by it—for temporary writing with overhead projectors, whiteboards, and the like. They may also be used by children when adults want to be able to clean up after them. The erasable ink does not contain the toxic chemical compounds xylene and/or toluene.
