This traditionally handmade Pi paper is made of mulberry tree* fibers for crafting and brush painting. Thin thickness, very tough and hard-wearing, it is made for Chinese brush painting and may also use as lamp cover and other paper crafting material. It is a kind of unsized, absorbent rice paper. We would recommend this beautiful paper to sumi students and professional artists to give it a try. *Mulberry tree leaves are the sole food source of the silkworms.
