A box comprising a bottom, a pair of side walls, and a pair of end walls is stackable due to the shape of the end walls and their interaction with the bottom of the box. The end walls include parallel, upwardly directed arches flanked by flat surfaces which prevent lateral relative movement of stacked boxes. Notching the bottom to receive the end walls such that they grip the bottom prevents longitudinal relative movement of the stacked boxes.
