This item has been stored in a chest for several decades without ever being used. I'm not sure what type of obi it is or what material it's made of, but the size is approximately 30.2 x 454 cm. As far as I can tell, there are no noticeable stains, but since it has been stored for a long time, I've marked it as "slightly damaged or dirty." Please refrain from purchasing if you are overly concerned about this. I apologize for my poor photography, but the close-up images are closer to the actual color. When shipping, I will fold it up, so it may wrinkle. Please understand. I would be happy if someone could use it for kimono lessons or for remaking. Thank you.
