This inkstone-based inkstone-based inkstone in Nampo-myeon, Boryeong, was called Nampo-brew because it is widely produced in the Nampo area. The inkstone was used since the fall, and during the Goryeo Dynasty, the use of the inkstone expanded due to the prevalence of Neo-Confucianism. Therefore, technology has developed and exports have been made since 1961.

The production process is finished by taking five stones, hand-crafting them, and sculpting different patterns and patterns. The patterns include traditional patterns such as dragons, phoenixes, pine trees, and bamboo trees. The characteristic of the Nampo broom is that its prey is well ground, and its ink remains dry for a long time.

The technique of making Boryeong Nampho Blossom was recognized as an intangible cultural asset because of its value as a cultural asset, and Kim Jin-han, the current holder of the function, continues its existence.
