The key holder consists of a rigid board, e.g. of a plastics material such as polypropylene, or of cardboard, to which keys can be attached by strips (2) of a self-adhesive material such as 'Velcro' (RTM). Each key (3) has its own identification tag (4) with a matching strip (6) of self-adhesive material on the back. The board has hooks (1a) at its upper corners to allow it to be stored in a filing drawer. It also has an aperture (7) which serves as a handle, and a magnifier (8) along its upper edge over an identification label.
