     DETAILED DESCRIPTION OF THE INVENTION 
     The key case of the invention comprises an ornamental openable housing 1 large enough in dimensions to house a house key. 
     A key fastening device 2 of any suitable known type is provided in the housing 1, as shown in FIG. 4, for removably mounting a house key 3 in the housing. 
     A housing fastening device removably supports the housing 1 on a person 4 (FIG. 1). The housing fastening device may comprise any device for removably affixing the housing 1 to an article of clothing or to the body of the user. In a preferred embodiment of the invention, the housing fastening device comprises a neck chain 5 (FIGS. 1 and 2) for suspending the housing 1 from the neck of the person 4. 
     The housing 1 may comprise any suitable openable housing of suitable dimensions such as, for example, as shown in the FIGS., two half housings 6 and 7 (FIGS. 4 and 5) hingedly affixed to each other by any suitable hinge device such as, for example, a hinge 8 (FIG. 4). 
     The neck chain 5 is affixed to the housing 1 by any suitably means such as, for example, a loop 9 (FIGS. 2, 4 and 5). 
     While the invention has been described by means of a specific example and in a specific embodiment, I do not wish to be limited thereto, for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
