Overview
A compact (also powder box, powder case and flapjack) is a cosmetic product. It is usually a small round metal case and contains two or more of the following: a mirror, pressed or loose face powder with a gauze sifter and a powder puff.
History
Compacts date from the early 1900s, a time when make-up had not gained widespread social acceptance and the first powder cases were often concealed within accessories such as walking sticks, jewellery or hatpins.
From 1896, American handbag manufacturer Whiting & Davis created lidded compartments in its bags where powder rouge and combs could be stowed. In 1908, Sears' catalogue advertised a silver-plated case with mirror and powder puff (price 19 cents) and described it as small enough to fit in a handbag.
In the US, manufacturers such as Evans and Elgin American produced metal compacts with either finger chains or longer tango chains. Designed to be displayed rather than fitted in a handbag, they required more ornate designs and many from this era are examples of sleek Art Deco styling.
