    Abstract: A multi-section body-painting crayon includes a plurality of hollow cylinders, each of which forms one section of the crayon. The cylinder is provided at front and rear ends with exterior and interior connecting portions, respectively. The exterior connecting portion of each cylinder is adapted to detachably connect to the interior connecting portion of another cylinder, so that the cylinders may be continuously connected end to end to form a long barrel for the crayon suitable for holding with one hand. A cake of paint of a specific color is fixed to the front end of each cylinder. A user may easily change the number, position, and color of the cylinders to be included in the crayon and conveniently carry the crayon for use at any time and place.
