Cosmetic Compact is usually contained in a small, round case, with two or all of the following: a mirror, pressed powder, and a powder puff. The term is an abbreviation for "compact powder". Eventually the more elaborate compact, the 'vanity case' became popular as it had more compartments for more makeup items.
Compacts prior to the 1960s are vintage and are very desirable as a collector's item. Made of many different materials and often depicting the era of when it was made. ie: Art Deco
