Tanggeon (horsehair mesh cap) was worn between the mesh hairband and official headwear by male members of the Joseon upper classes whenever they appeared in public in formal dress. It was also worn by middle class adult males as an independent item of headgear. This particular item is made of horsehair woven rather loosely, while the case is made of paper and wood, decorated with a design of “Five fortunes of five bats” on the bottom, and has a hinged lid with closing latch.
