Abstract: A knock-down case kit for different size contents including size panels having dovetail grooves slidably receiving complemental slides on the bottom edges of mirror-image top, bottom, front and back panels. The two bottom panels are hingedly connected to each other and a handle and complementary latch element are detachably coupled to the top panels. In order to vary the depth of the assembled case, alternate size top, bottom, front and back panels are provided in the kit which may be substituted for like panels. Each panel is made from transparent plastic so the contents may be displayed without opening the assembled case.
