・Blue ・Light Green ・Ivory ・Misty Blue This is a set of four genuine silk (正絹) "sanbu-obi" cords. They are easy to tie and show signs of use and some staining. I believe they are genuine silk, but I apologize if I'm mistaken. I think they would be good for practice. As they have some stains, I'm offering them at a low price. Thank you.
