A case composed of at least two shells. In a preferred embodiment, two semi-cylindrical shells are provided. The shells are coupled for relative rotation about an axis and are sized so that each shell segment nests within an adjacent shell. The shells are rotatable between a closed position, in which the shells cooperate to define an enclosed compartment, and an open position, in which said shells nest inside one another to provide access to the compartment.
