The invention is directed to a two piece shipping package such as a substrate shipping container that is used to ship solar cells or other substrate wafers and locking device for use therewith. One or more latching members having permanent and multi-use tab features are used to join the components of a readily constructed container. The container is generally made up of two identical container portions, each container portion having a horizontally-disposed base member and two vertically disposed side members constructed of impact-absorbing double walls. The locking device provides an integrated locking snap connector that holds two container portions together at opposing corners, the containers of which are generally shaped for being readily coupled with one another in reversed and inverted orientations.
