1. A container operable within a storage system having similar containers interlockable in a vertically stacked configuration, the storage system useful in organizing and storing articles, the container comprising opposing top and bottom walls, wherein an upwardly projecting tongue extends from one of the container walls, the tongue having outwardly diverging side walls terminating in a tongue edge portion, and wherein a cavity within the opposing container wall has opposing side walls converging toward a cavity opening for receiving the tongue of an adjoining similar container therethrough and attaching the tongue within the cavity, the tongue and cavity each formed as an annulus extending proximate peripheral top and bottom wall edge portions, the cavity side walls cooperating with the tongue side walls while the tongue is attached within the cavity, the cavity opening being slightly smaller than the tongue edge portion, the tongue and cavity formed from material sufficiently flexible for permitting the tongue edge portion from the adjoining container to be forced through the cavity opening for positioning the tongue within the cavity, thus coupling the adjoining containers in a vertically stacked and interlocked position.
