シャトレーヌ（女城主）とは中世の時代に戦いにいく男性が妻に城の鍵を預け、その女性がたくさんの鍵を腰につけるための装身具を指します。
それをデザインのヒントにしたこのコンパクトは、ピン飾りに香水、コンパクト、ペンが垂れ下がっています。

When medieval knights went off to battle, they left the keys of their castles to their wives, who hung them around their waists on chains that came to be known as “chatelaine” (literally “lady castle owner”).
The chatelaine is used as the design motif of this accessory. It is accessorized with a perfume vial, compact, and pen hanging from a decorative pin.
