Abstract: Disclosed is a box assembly for packaging objects, the box including a lower portion and an upper portion, one portion slidably fitting onto the other portion. The box includes a flat lower wall section; a flat upper wall section, having a different surface area from the lower wall section; and a pair of elongated side wall sections. The side wall sections include a plurality of spaced apart tabs extending from one longitudinal edge of each section. The tabs can be folded at substantially right angles to the elongated side wall section. The tabs of one side wall section can be adhered to the perimeter surface of the lower wall section, and the tabs of the other side wall section can be adhered to the perimeter surface of the upper wall section. When the elongated side wall sections are adhered to the lower and upper wall sections, respectively, the lower and upper portions of the box are formed. A method of packaging objects with the box assembly is also disclosed.
