The utility holder was designed to allow stored markers an extended life of working effectiveness. The design has one or more cylindrical recesses with a tapered bottom in which a dry-erase marker cap may be held in place in order that a dry-erase marker may be placed inside the cylindrical recess upside down, snapping into the dry-erase marker cap. The upside down placement of the markers in the magnetic whiteboard utility holder allows the markers maximum life. There are one or more magnets on the back surface of the utility holder which allows for it to adhere to a magnetic whiteboard. The utility holder also has a cuboid recess, which allows for a dry-erase eraser to be stored.
