This is a lovely Tsumugi Nagoya obi
with colorful flower pattern, which are roughly woven on the deep navy colored background.
Textile is silk and synthetic blend, and has soft touch.
It has prominent discoloration on the base with ages.
Snag(A) can be seen on the otaiko(square bow), but not disturbing if it's cut off.
There are some other flaws such as stains and folding lines.
For the details, please refer to the photos and the sheet.
Although not indicated, whitish molds can also be seen overall.
It must be an amazing handicraft material to enjoy its lovely design.
