It's a work that reproduces the relics of Jiseung Korean chamber pot which is called 'Yogang' from the Joseon Dynasty.
This work is made of Jiseung, and 'Jiseung' refers to a paper string made by cutting long a piece of Korean paper made with a unique Korean technique and twisting it together.
So it is very light and strong compared to its bulkiness.
When the women of the noble households moved long distances riding palanquin, they carried and used a light 'Jiseung Yogang'.
It was mainly lacquered for waterproofing.
