Vanity cases are small containers used to store and transport personal items such as makeup, jewelry, and other accessories. The term 'vanity cases' can be broken down into two words: 'egos' and 'etuis'. Egos is a four-letter word derived from the Latin word for 'I', while etuis is a five-letter French word meaning 'CASE'. Vanity cases are typically made of leather or plastic and come in a variety of sizes and shapes. They are often decorated with intricate designs and can be used to make a fashion statement.
