ABSTRACT:
This invention discloses an erasing device that can be held in the same manner as a writing instrument. The eraser is stored in a tube assembly and a rolling mechanism is used to slide the eraser out of the tube assembly for use. The rolling mechanism prevents the eraser from accidentally sliding back into the device during use and gives the user total control over the length of eraser that is extended from the device.
