Abstract: A storage assembly is provided for the accessible storage of small tools and components. The assembly includes a rectangular open-topped outer container having internal length and width dimensions that are selected integer multiples of a selected dimension. The outer container may have hand grips formed in the sidewalls in proximity to the open top for lifting the outer container and the entire assembly. The assembly also includes a plurality of rectangular open-topped inner containers having length and width dimensions that equal the selected dimensions employed in the outer container. Thus, if the inner containers have length and/or width dimensions of X, the outer container may have length and width dimensions of 3x and 2x respectively. Thus, a plurality of the inner containers may be stored efficiently in the outer container. The inner containers are configured to be stackable so that a plurality of tiers of inner containers can be stored in the outer container.
