This is a Tsumugi Fukuro obi
with botan(peony) or sasa(bamboo grass) arabesque pattern.
It has been woven on kiredori(over lapping fabric scraps) with kikko(tortoise shell) or shippou-tsunagi(jointed four circles).
Textile is silk and has soft touch.
There is no folding lines and it seems to be unworn one.
It has some small stains at just otaiko(square bow).
However, they will be hidden when it tied if you tie well.
For the detail, please check figures and photos.
If you do not mind these flaws, it still can be tied.
Please enjoy its elegant design casually!
