A Ido-type white porcelain sake cup fired in the latter half of the Joseon dynasty. The greyish-white poecelain is covered with crackle glaze finish, and Kairagi glaze is formed on the base. This type is thought to be the work of a folk kiln in the southern part of the peninsula, and is often referred to as the Ido type because of its feature.

It has a good weight and the texture is excellent. As well as a sake cup, the thick wall is ideal for hot tea. There is no notable damage other than a minor hairline on the rim.
