Stackable and plug-in box, consisting of a single molded piece, generally inverted quadrangular truncated pyramid shape, symmetrical with respect to the transverse and longitudinal vertical median planes and whose four side walls, converging towards the base, have their upper edge bent first outwards, according to a short first horizontal section, and then downwards as a skirt, according to a short second vertical section, characterized in that in said short first horizontal sections of the upper edge of the box, two step notches are made on each side thereof; that are born in the center of the side, they diverge outwards at an acute angle with respect to the median longitudinal vertical plane of the box and die in a slightly deeper concavity arranged adjacent to the respective corner of the box, all this so that two boxes identical overlays can be plugged into each other when their symmetry planes coincide, while the the upper part of these can be supported on the lower one by a previous turn of an acute angle equal to the one of divergence of the step notches, in one or the other direction, the lower edges of the upper box being fitted in the respective notches of the upper edge of the box lower.
