A stackable box formed from a one-piece blank cut of corrugated paperboard material has integrated right-angle stacking tabs protruding upwardly from each top corner of the box which matingly interlock with openings on each bottom corner of a second similarly constructed box so as to prevent sideways slipping of the boxes when stacked. The box folds and assembles without the need for fasteners, glue or other parts. The sides are assembled to have four-wall thickness and the ends are assembled to have two-wall thickness for improved strength.
