Object-holding case consisting of a generally flat casing that comprises a generally flat box-shaped body (4) closed by a generally sheeted body (3), where said generally flat box-shaped body (4) has an articulation area (66) that divides it into two parts (40, 42), the first of which (40) is fixed to said generally sheeted body (3) so as to provide a containment space (1) for objects (2), whereas the second (42) can oscillate with respect to the previous one (40) so as to open and close said containment space (1).
