This is a modern summer 'ara-sha' (rough sha) Nagoya obi
with geometric pattern which is roughly woven.
Textile is exquisite silk, and it has crisp and very stiff touch.
There are rather prominent streak-like discolorations due to frays on hem and upper otaiko part(*described as stains on the figure).
Please check photos and a figure for details.
It will be still wearable if you don't mind minor flaws.
Its versatile design allows you to enjoy matching variety of kimonos to give your kimono fashion different look.
