The pieces are made of Yuhang bamboo paper. They follow the same production process as it is still used by local paper workshop – ancient handmade paper. There are no further additives used to generate a strong and solid shape. Due to the natural qualities of the fiber a proper result in terms of durability is already given. The irrefular edge as well as the rough outside surface is illustrating the process of handmade paper and the unique character of each piece.
