Dwikkoji is a Korean traditional ornament used to decorate ladies' chignons, and it has a sharp end. When ladies stick the dwikkoji in their chignon, it functions as jewelry adorning their hair.[1]
Three-leg golden dwikkojis are presumed to have come from the Baekje period of Korea, and they are believed to be the origin of dwikkojis in general.[2]
The different types of dwikkojis correspond to social status: some are for royalty, others for nobility and others are for ordinary people. The most common dwikkojis for ordinary people are called bichigae (comb-type) and guiigae (earpick). They are usually made of silver, and they both have elements of fanciness and practicality.[1]
