It has a Ryukyu-esque color scheme, with a kasuri pattern (ikat binding) woven with swallows and coin motifs within the Goma-i pattern. It reflects a slightly iridescent color when exposed to light. It's slightly thicker than Oshima Tsumugi. The certification label has peeled off and been lost, but there is a woven selvedge, so there is no doubt that it is genuine.
