This is a Fukuro obi
with gorgeous flower 'Marumon' (circle) of 'botan'(peony), fuyou and Iris, which is woven among water streams and sparrow base pattern.
Textile is silk, and it has soft touch.
It must have used to tie a fancy bow as there is a folding line on Tare end.
It is discolored throughout, and light colored parts of the pattern seem slightly discolored, however, they are barely noticed.
It also has some stains.
Please see photos for details.
Although it has some flaws as mentioned, it still is a very charming item to wear!
