I don't know how to use it, so please purchase only if you know how. The contents are only the two items in the photos. The red obi is about 120cm long. It has been stored at home. The white string part is slightly discolored. Please purchase if you understand that it has been stored at home for a long time. If you wish to have cushioning material or tracking, please consult with me in advance. If you have any questions, please ask in the comments section (*^*)
