This is a Fukuro obi
with exotic sarasa 'chintz' and deers motif on a dish pattern, which is woven.
Gold foil threads included in fabric and the pattern twinkle gently.
Textile is silk, and it has soft to the touch.
Length is 414cm,(4'52") rather short.
Foil threads included in the fabric are frayed and peeling. (sorry no photos)
Same type of peeling spots are in places and they are noticed.
It has some other flaws, such as rather prominent folding lines, as shown on photos.
Please see photos for details.
If you do not mind the flaws mentioned, it can continue to be worn.
