This is a vintage Nagoya obi
with a design of shrimp and turban shell on stream, which is woven.
Gold and silver foil threads woven in the design are elegantly shining.
Textile is silk and jinken (rayon) blend, and has soft touch.
Its length is rather short, 10'10"3/8(331cm).
Stains on otaiko can be hidden when tied.(5th flaw photo)
Patinas can be seen overall, but they are tiny so not disturbing when tied.(3rd flaw photo)
There are other flaws such as folding lines.
Please check detail photos.
Though it has some flaws by ages, please enjoy its full taste of vintage!
