Crown Prince Sado's Sandals

Were the sandals worn by Crown Prince Sado, who was the royal heir to Yeongjo of Joseon. He was thought to be or accused of being mentally ill. The king told Sado to climb into a large wooden chest and closed it, where he died from suffocation eight years later. The sandals allow a person to survive without the basic needs for life, such as food, water or oxygen. It also allows a person to be compacted easily into smaller spaces.
