This invention relates to a key holder case, in general,
?at so that the edges are either side edges or ends without
requiring quali?cation as to top or bottom.
The plates 11-15 have a reverse symmetry such as
enables keys to be pivotally mounted at each end of the
plates and be received within opposite side edges thereof.
The reversed symmetrical form of the case is thus both
functional and pleasing in appearance.
A projection 20 is formed at each end of each of the
