Gray woven kakugo obi. Kakugo obi, men's, summer wear Approximately 4 meters Material: Ra (a type of gauze) Ra is a thinly woven silk fabric with a coarse weave and excellent breathability, making it suitable for summer wear. The word "ra" originates from the "net" used to catch birds, and it is woven with the warp threads intertwining with each other on the left and right. This creates a strong and durable fabric despite its open weave. Ra is similar to knitting, so it cannot be made with a standard loom. - Color: Gray - Material: Woven fabric Thank you for viewing.
