A four-ply paper board hanging hole in a display box for hanging a display box from a support rod. This is accomplished by the use of a paper board die blank having a hanging hole in four layers of the box such that, when the box is assembled, the four hanging holes are aligned to provide a strongly reinforced hanging hole which proves quite difficult to rip. Therefore, an increased aesthetic appearance of the display box is achieved, resulting in increased sales and minimal wasting of display box products.
