This headband, which is called a manggeon (literally meaning “net band”), was tied around the forehead by married men during the Joseon period to secure their hair while wearing a topknot. It was made from the long, coarse hair of the manes and tails of horses. The headband was removed and stored in a case while sleeping at night. The case typically had either a single loop on the top or two at the sides from which it could be hung on the wall when not in use.
