A Magic Marker is a coloring device that uses any of many colors to flow through a rather large felt point. They are about the size of early elementary crayons -- the fat ones --but there's a flow of ink rather than color put down through a wax medium.

I suppose you could call them colored markers... but I cannot think of a good generic term. Felt tip markers wouldn't really work because those could be the pen-sized ones.

Hmmm.... Who's got the answer?
