A packaging device for a flat object is shown The device is constructed from a flat material The material has a central folding line, two rectangular areas symmetric with respect to the central folding line The rectangular areas each have a triangular area formed by folding lines Sidewall section areas are formed adjacent the triangles Object support flaps adjacent to each of the sidewall section areas are formed The support flaps each having a right angle cut delineating a flexing sub-triangle region The device has a folded position where the support flaps are folded inward and the material is folded along the central folding line such that the support flaps are contained between the rectangular areas Opposing sub-triangle regions are attached providing a storage space for the object The device has an unfolded position where sidewall sections fold inward forming a 3D tetrahedron shape and the object can be displayed.
