A box construction is characterized by double-layered side walls and by a paper wrapping extending over the exterior surface of the box and extending partially over each interior side wall and each interior end wall. Each double-layered side wall consists of a single thickness of paperboard, partially covered on one side with paper wrap and folded inwardly over itself, so that the external paper wrap extends over the interior side walls to form a paper lip, giving the interior of the box a desirable "finished" appearance.
