Markers

Perhaps not the most sophisticated art medium, but one of the first people are introduced to. In arts and craft times everybody would fight for the good markers at risk of being stuck with the crayons or horribly unsharpened pencils.
Markers are bright and bold. They make a statement by going down on paper. Highlighters are extremely flamboyant markers and Sharpies are the markers for grown ups. Expo's are the school marker and thin tipped markers are stupid. You know those ones that have super fine tips and about enough ink inside them  to make a solid line? The ones that come in 100 packs with a zillion colors and die the first time you use them? I don't like those markers.
As far as art supplies go markers don't really get used a lot. In elementary school they are great but once you hit high school most classrooms don't come equipped with the full set of colors, if any at all. One of my teachers has a box of orange, brown, gray, and yellow markers. Quite an ugly rainbow. It's just not a priority material. In any class below 6th grade it'd be a sin to not have at least 2 complete sets per child so you have a reliable back up when needed. Once you hit puberty it becomes an insignificant item. Personally I've always liked markers. Not for professional level projects, but because they are bright, clumsy, simple, and not perfect. Just like me. Just like a lot of people.
