This is a vintage Nagoya obi
with flower bouquet on rhomb lattice pattern, which is woven.
Textile is silk and has soft touch.
It might be made by Maru obi
fabric as a remaking.
There are fray and blackish smudges so it may have been re-tailored.
Also it has other flaws, so please check detail photos.
Although there is no figure and photo, it is discolored overall and has peeling foils.
Also it has put a patch from tare-saki(end of the wide part) to tare-top(triangle part), almost middle of the obi.
(refer to the 2nd photo of entire)
Textile is may be weak, so it seems not to be suitable.
However, we hope you can enjoy its tasteful design of vintage at your hands!
