Abstract: A stick object storage box adapted for holding for example floss sticks, including a rectangular box body, and a sliding cover coupled to the box body by a slip joint, the sliding cover having two inward stub rods bilaterally disposed at the front end and moved in two longitudinal sliding grooves at two opposite sides of the box body. By moving the inward stub rods in the longitudinal sliding grooves and turning the sliding cover relative to the box body, the box body can be supported on the sliding cover in a tilted position in an open status.
