A stackable container that can be stacked with containers of various sizes, and that increases available storage volume without increasing weight. The defective pixel detection and correction mechanism also replaces defective pixels with stable replacement values. The container further includes partitioning dividers extending to the bottom wall to divide the internal space of the container into vertically oriented compartments. The elongated top tubular member is attached between each of the parallel side plate members at the top edge so as to connect to each side plate member.
