This is an Fukuro obi
with glossy housouge(imaginary flower in China) design, which is woven.
It used silver foil threads richly, it is perfect for formal occasions.
Textile is silk and has soft touch.
Stiff lining is not added inside.
There are patinas overall, and it is noticeable at maegara(front design) especially.
However, if you start wrapping the obi from your left tummy to right(rotate obi clockwise), almost patinas will be hidden.
Also it has rather prominently folding lines and so on, so please check figures and photos for more details.
If these flaws do not bother you, it could be still used.
Please enjoy its gorgeous design!
