This is a Fukuro obi
with silver and gold Ryoushi 'confetti' and Kasumi'mist' pattern, which is woven.
Foil threads included in fabric and the pattern twinkle gently.
Textile is silk, and it has soft touch.
It says 'Min-Tsuzure' inside of Tare end and looks as if the obi is tsuzure weave.
Folding lines will show if tied as double layered Otaiko, as seen on the photo.
However, if tied as single layer, lines will not show.
Discoloration is too light to be noticed.
Please see photos for details.
Although it has some flaws as mentioned, it still is a very charming item to wear!
