Genuine silk, nine-sun obi (belt), summer obi. Although it's designated as a summer obi, the weave feels rough, like a wall weave, and it's not sheer. I suspect it might be too warm for the peak of summer. It features a pinkish-brown base with woven, subdued gold threads. The overall appearance changes depending on the light, appearing bright or dark. 31cm x 350cm. Because it's shorter, it's recommended for petite or slender individuals.
