Abstract: Modular storage units are formed for small, household articles so that the units can be stacked vertically one atop another. Each unit is formed with a box supported from beneath by a stand for rotation relative to the stand about a central, vertical axis of rotation. The stand has a base that covers a horizontal stand base area and supports the flat bottom of the box. The top of the box is flat and has a concave, upwardly facing recess at its center that has a shape configured to snugly received the stand of a unit stacked directly above. Any number of modular storage units can be stacked one atop another with the stand of each unit being centered and laterally confined by the stand receiving recess in the top of the box located immediately below. In this way all of the boxes are rotatable independently of each other about a common, vertical axis of rotation. The contents of the boxes may be accessed either by forming the box with an open side, or by forming each top of the box as a removable lid.
