This is a Fukuro obi
with classical 'Karabana' (imaginary flower in china), 'Kiku'(chrysanthemum), 'shokkou-mon' (octagon and rectangle pattern) and 'shippou-tsunagi' (interlocking circles) pattern, which is woven.
Flat foil is used for warp, and it gives a shine like Saganishiki brand.
Textile is soft silk.
It does not have any folding lines, and it seems unworn.
It has no noticeable flaws, and it is in very good condition overall.
This obi should make your kimono outfit very stylish!
