ABSTRACT:
A marker eraser system for efficiently combining an eraser with a dry erase marker. The marker eraser system includes a body having a tubular structure and a central aperture extending through the tubular structure. The central aperture extends through an inner end to an outer end of the body. An eraser member is attached to the outer end of the eraser unit to erase a removable ink from a dry erase marker. An outer end of the central aperture frictionally receives an outer portion of a first end of a cap of the dry erase marker to allow a user to removably attach the marker eraser system to the cap of the dry erase marker.
