Editing Marker pen (section)

==Types==

===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.

===Highlighters===

Highlighters are a form of marker used to highlight and cover over existing writing while still leaving the writing readable. They are generally produced in neon colours to allow for colour coding, as well as attract buyers to them.

===Whiteboard markers===

A whiteboard marker— or dry-erase marker— uses an erasable ink, made to be used on a slick (or matte-finished), non-porous writing surface, for temporary writing with [[overhead projector]]s, [[whiteboard]]s, glass, and the like. They are designed so that the user can easily erase the marks using a damp cloth, tissue, handkerchief, baby wipe, or other easily cleaned or disposable items. Generally, people use fabrics to do so, but others use items like paper, clothing items, some even use their bare hands to wipe it clear. The erasable ink does not contain the toxic chemical compounds [[xylene]] and/or [[toluene]] as have been used in permanent markers, being less of a risk to being used as a [[recreational drug]].

[[Wet-wipe marker]]s— or wet-erase markers— are another version that are used on overhead projectors, signboards, whiteboards, and other non-porous surfaces.

===Security marker===
Special "security" markers, with [[fluorescence|fluorescent]] but otherwise invisible inks, are used for marking valuables in case of [[burglary]]. The owner of a stolen, but recovered item can be determined by using [[ultraviolet light]] to make the writing visible.

===Election marker===
Marker pens with [[election ink]] (an indelible dye and often a [[photosensitive]] agent such as [[silver nitrate]]) used to mark the finger, and especially the [[cuticle]], of voters in elections in order to prevent [[electoral fraud]] such as double voting. The stain stays visible for a week or two and may also be used to assist in [[vaccination]]s.

===Porous point pen===
A ''porous point pen'' contains a point that is made of some porous material such as [[felt]] or [[ceramic]]. [[technical drawing|Draftsman]]'s pens usually have a ceramic tip since this wears well and does not broaden when pressure is applied while writing.
