Markers are used by educators, office professionals, artists, and others to create, label, draw, and write. In art classes, students use alcohol- and water-based markers to create original works of art on paper or other surfaces. Metals and other materials can be marked using permanent markers to help identify them without the use of extra stickers. Dry erase markers can be used to mark glass or ceramic surfaces while you work on them and then removed once the required cuts or adjustments have been made.
