I believe this is Chinese art, but the details are unknown. I purchased it online, but I didn't use it, so I'm selling it to organize my belongings. I think it's cool not only for calligraphy but also as a work of art. Please understand that it is a used item, as it appears to have been used before purchase. Please refrain from purchasing if you are sensitive to the condition, as it has been stored by a private individual.
