Abstract: A writing instrument includes an elongate body having opposed first and second ends, a longitudinal axis and a bore therein extending from the first end. A marking body, such as one having lead or a colored material, extends from the first end and is seated in the bore, while a connector is coupled to the second end. An eraser, such as a rubber eraser, is coupled to the connector and is configured to erase markings made by the marking body. The eraser includes a flat surface that is configured to prevent the writing instrument from rolling about the axis down an inclined surface contacting the elongate body. The flat surface may be oriented on a plane that is substantially parallel to the axis. The flat surface may also include a dimension perpendicular to the axis that is larger than another dimension of the elongate body which is also perpendicular to the axis.

Abstract: The crayon assembly includes a crayon and an eraser. The crayon is made of a material which can make a mark on paper and which is capable of being erased from paper. The crayon assembly may also include a label. The crayon may include an attachment portion which may be a pocket. The eraser may include an attachment portion which may be a post. The post corresponds to the pocket. The attachment portions may have different shapes and/or cross sections. The crayon may be connected to the eraser by molding. In other embodiments the eraser may be connected to the crayon by an adhesive, by a ferrule or by other configurations.
