This is a vintage Nagoya obi
with unique arabesque like geometric pattern, which is dyed.
It has been woven flower on tatewaku(waving line) pattern on the the wrong side.
Textile is silk and has soft touch, and the wrong side is jinken(rayon).
Rather thick lining is inside.
There are small frays and tears at edges, and it is getting weak.(the 6th photo of flaws)
Loosing stitches at tare-saki(end of the wide part) looks be spread.
Also it has other flaws, so please check detail photos.
Although there is no figure and photo, slight and small patinas are seen overall.
It doesn't have enough strength to be tied due to its age.
However, we hope you can enjoy its stylish design of vintage at your hands!
