This is a summer Tsumugi Fukuro obi
with rough woven pattern.
Textile is Tsumugi
silk, and it has nubby touch with slight sheer look. (the wrong side also has sheer look)
Brown color lining is inside, and it shows through between the yarns, which is quite stylish.
It has no folding lines, and it seem unworn.
Some stitches of the edges are loosen. (sorry no photos)
It has some other flaws as shown on photos.
Please see photos for details.
Loosen stitches on edges must be repaired in order to wear.
