This is an opened Nagoya obi
with geometric 'yoroke-jima'(wavy stripe) pattern, which is dyed on the gradational background.
Textile is exquisite silk and has soft touch.
There is no kaikiri(end mark) line, so it seems to be made from kimono fabric.
Although not shown on the photo and figure, it has smudges about 1.6in(4cm) on the crease upper otaiko, but it can be hidden when tied.
Besides it has a snag so please check photos for details.
It's still wearable enough with very good condition.
Please enjoy its fashionable piece as a daily wear!
