Thank you for viewing. Although there is no silk material certificate, this is a plump Hakata-ori (Hakata weave) style? A modern geometric pattern, a 6-way obi (sash) without a core. It has been used a few times. There is some wear and tear, and a small, inconspicuous stain on one side. I have taken a picture of it in the 13th photo. Overall, I think it is in a clean condition without any noticeable stains or dirt. This obi is very easy to tie. It is a used item that has been stored at home, so please purchase only if you understand this. Silk material Width 31 cm, Length 425 cm
