Abstract: A box for containing goods during storing, delivering, mailing, or shipping. The box has at least one end panel secured to a body panel by a locking tab and slot assembly so that the end panel cannot be unsecured without providing visible evidence of tampering. The leading edge of the locking tab has at least a partially tapered profile when the tab is folded for insertion through the slot. The slot may be curved to provide additional abutment between the associated locking tab and slot assembly. The container may have decorative motifs printed on the exterior surface to resemble a gift-wrapped box or a box having a unique or characteristic graphic design.
