This obi is made of a double layer of heavy satin material. The embroidery is exquisite. Most of it is done with silk thread but there is also some metallic thread. There is something else that looks like thread that has been covered with a thin layer of brown lacquer. The obi measures 12.50" wide and is 160" (4+ yards) long. There are some stains that I have shown in a photo. I haven't had it cleaned so they may come out. Really a gorgeous traditional Japanese piece.
