A container includes a pallet, an enclosure base, an enclosure box, and a set of fasteners. The pallet is disposed at a bottom of the container. The enclosure base is placed on the pallet, and includes a lower base sheet and an upper base sheet. The lower base sheet forms a first pair of side flaps. The upper base sheet forms a second pair of side flaps. The enclosure box is placed on the enclosure base, and includes a top wall, a set of four side walls, and an open bottom. The four side walls of the enclosure box rest on the lower base sheet while surrounding the upper base sheet to position the first pair of opposed side flaps outside the enclosure box, and the second pair of opposed side flaps inside the enclosure box. The set of fasteners fastens the enclosure base to the enclosure box.
