The water dropper was one of the main tools for writing. It holds water inside when ink-stick was grinded. It is also possible to control water volume. The demand of dropper in Joseon period kept rising because Joseon had a favorable writing culture. This is a square-shaped dropper and the decoration patterns are pine tree and crane.
