Gampi fibersyield a strong, crisp sheet that is translucent with almost no visible fibers. These papers have a very smooth surface and a satin-like sheen.
The Gampi bush is found in the mountainous, warm areas of Japan and has been used as a washi-making material for many years due to the high quality of the fiber. Because it cannot be cultivated and is time consuming in the cleaning process, Gampi is the most expensive of the Japanese papers.
