This is a gorgeous Fukuro obi
with traditional pattern, which is woven with shiny gold foil threads.
Seigaiha(consecutive wave) and kikko(tortoise shell) pattern are seen.
Textile is silk and has soft touch.
This piece may have been tied in unusual knot style, it has folding lines overall.
However, it doesn't have any other prominent flaw.
So it's still wearable enough with very good condition.
Please enjoy its fascinating design, it will brighten up your kimono fashion for sure!
