Similar to the RSC but without top flaps, the HSC or Half Slotted Case is often used in warehouses and workshops as storage boxes. Seal the bottom with tape, and the top can be covered with another HSC or a tray.
Telescoping HSC. If your products are oversized and flat, a pair of telescoping HSCs could be the ideal solution. One fits inside the other and they slide together for a good fit. They are also great for products of variable size.
