This is a Fukuro obi
wih vibrant doukyo 'copper mirror', animals , and 'Karabana' (imaginary flower in china) pattern, which is woven colorfully against black base color.
Textile is silk, and it has soft to the touch.
Both ends are open, and it does not have a stiff lining inside.
There are snags in places, but not disturbing for wearing. (sorry no photos)
There are more spots of white mold on the blank area, but they will not show when tied.
It has some other flaws, such as slight folding lines, as shown on photos.
If you do not mind the small flaws mentioned, it can continue to be worn.
