Design Style Tray

A design style tray is similar to an OPF: both are generally flat and square. However, a DST has flaps on the sides and the ends that are folded and fastened to produce a tray. Though the tray can be used by itself, DSTs are often used with a corresponding (and slightly larger) DST-LID. DSTs are also often used as lids for HSCs. Typical applications: shipping heavy flat items, re-usable storage container.
