    Abstract: The disposable dry marker eraser is a reusable eraser body and a disposable cleaning sheet removably attached to the bottom surface of the eraser body. The bottom surface of the eraser body may have an adhesive coating, or a hook fabric fastener may be affixed to the bottom of the eraser body. The cleaning sheet is made of a pile fabric, which is removably attached to the adhesive coating, or releasably mates with the hook fastener. The dry marker eraser may be furnished in kit form, including a dispenser box containing a vertical stack of cleaning sheets and having U-shaped cutouts in its side walls, so that a user can insert the eraser body into the dispenser box and apply pressure to attach a replacement cleaning sheet, the box aligning the sheet with the eraser bottom and the cutouts accommodating the user's hand as the stack of cleaning sheets dwindles.
