An elevated tiltable storage assembly for the storage and retrieval of goods. The pocket holding the article inside the mailer is offset relative to one edge, when folded, by a distance sufficient to prevent damage when the mailer is oriented and processed. Loose materials are gathered and picked up by placing one hand on the shaft of each grasping element and drawing the heads together. The direction of the path is reversed on reaching a last level or a last row of the network. A preferred embodiment includes means for supporting a football, means for mounting to various support surfaces, means for supporting an air pump, and means for storing needle valves. A second number of electrodes are alternately disposed with the first number of electrodes within the first ring and are further operable to measure variations in the electric field attributed to a position of the object.
