This is a Nagoya obi
with elegant 'Kiku'(chrysanthemum) and 'Ume' (plum blossom) 'Marumon' (circle) with yuki Shiba(grass) pattern, which is dyed mainly in gold.
Fine embroidery work is added on parts of the pattern.
Textile is silk, and it has soft to the touch.
There are small whitish stains above Otaiko, but they will not show when tied. (sorry no photos)
Stains on Maegara will not show if you start wrapping the obi from your right tummy to left(Rotate obi counterclockwise).
It has some other flaw, such as folding lines, as shown on photos.
Please see photos for details.
Overall, it is in very good condition and can continue to be worn!
