FIELD: storage of small valuable or dangerous articles or documents. SUBSTANCE: Casing has bottom, side, end walls and cover with built-in reflective hologram depicting hollow casing or contents of it: articles, different from those actually present in casing, or articles-copies of articles stored in casing but having defects making these articles unfit for further usage. Articles presented on hologram may be fastened so that fastening members are distinctly seen on hologram. Holograms may be built in several flat outer surfaces of casing to enhance illusion of transparency of casing. Thus, outer examination of casing does not give reliable information on content of casing or gives incorrect information. EFFECT: reliable storage of valuable articles. 2 cl, 6 dwg |
