Abstract: A storage case for a center-mounted information carrier includes two hinged parts formed of plastic—namely, a base and a lid. The base free ends is a generally smooth, bilaterally symmetrically curve formed by an upstanding flange of substantial thickness, while the lid free end is a generally smooth, bilaterally symmetrically curve. The lid free end terminates short of the base free end so that the base free end can protect the lid free end. The storage case has a generally smooth exterior yet intuitively communicates to a potential first-time user how the case should be opened.
