Likely silk (正絹). 30cm x 4m Overall, there is discoloration and dullness, with stains in places. It's a bit difficult to use as is. However, because it's an all-over pattern (全通柄), there are two patterns where the stains don't affect the design. It seems usable if you cut out parts and remake them into a Nagoya obi. Alternatively, it could be used for making small items.
