a box shell formed of corrugated sheet material and forming a single drawer space of a shell bottom wall, shell top wall, opposite shell side walls with an inside facing surface of each facing centrally in the box shell, and shell rear wall with open shell front, wherein said shell bottom wall and shell top wall establish said box shell of single drawer height there between, said shell side walls define a plurality of fastener receptors located remotely from the shell top wall and shell bottom wall such that a minimum distance from a said fastener receptor to the shell top wall or shell bottom wall is shorter than the single drawer height of the box shell; a pull drawer formed of corrugated sheet material and fitting within the box shell, extendable from said open front, and formed of a drawer bottom wall, opposite drawer side walls, drawer front wall, and drawer rear wall; a plurality of fasteners having a head of predetermined diameter at opposite ends thereof, engagable in the fastener receptors with said heads extending above the inside facing surfaces of the shell side walls, and of length between said heads sized to join together two shell side walls of said corrugated material in abutting relationship, thereby enabling the lateral joining of like additional storage boxes; wherein the fastener receptors are spaced from the shell top wall and shell bottom wall by a distance suitable to accommodate receipt of one of said fasteners in one of the fastener receptors; and a sleeve lining said box shell, covering the extending fastener heads, and providing an intermediate layer between the outside surface of the shell side walls, including the extending fastener heads, and said pull drawer whereby the extending fastener heads, when applied at the receptor locations, are prevented from catching the pull drawer. |
