A container comprises a sheet of polymer formed into a base portion. The base portion has cavities for receiving frangible items. An intermediate cover portion has cavities for covering the frangible items. A first hinge rotates the intermediate cover portion onto the base portion to hold the frangible items captive. A top cover portion has at least one concavity. A second hinge rotates the top cover portion onto the intermediate cover portion to hold the base, intermediate and the top cover portions closed together. Flanges define peripheries of the base, intermediate and top cover portions. The intermediate peripheral flange has a cut-out at each corner of the intermediate cover portion defining a cut-out edge that is non-parallel to the longitudinal edges of the base portion, and has a dimension greater than a corresponding lateral flange portion of the top peripheral flange in a longitudinal dimension of the container.
