Center Special Slotted Carton (CSSC)
Inner and outer flaps are cut to different lengths. Both pairs of flaps meet at the center of the box. The style is especially strong because both the top and bottom have double the thickness of corrugated board. The inner flaps, with no gap, provide a level base for the product. A variation of this box is the Side Special Slotted Carton-SSS. All pairs of flaps meet, but not at the center of the box.
