This is a modern Fukuro obi
with ritzy facing two phoenix
and 'karabana' (imaginary flower in china) in Michinaga-dori ( shape of segments of Washi papers ) pattern, which is woven.
Gold foil threads included in pattern adds extra shine to the obi.
Textile is silk, and it has soft touch.
It does not have any folding lines, and it seems unworn.
There are whitish spots of mold on blank parts.
Please see photos for details.
Overall, it is in very good condition and can continue to be worn!
