The listing, Kpop bag rare has ended.
This was sold by "Ceci" during the charity auction.
Tiffany donated her costumes to Ceci and this bag is one of them.
It was specially designed and made by "Bean Pole" for SNSD TAETISEO.
Bean Pole manufactured three bags; one pink, one orange, and one blue.
Each of them was dedicated to TAETISEO members.
I'm not sure with which member owned this orange bag.
Tiffany owned pink for sure so this orange one is either Taeyeon's or Seohyun's.
Bean Pole named it "TAETISEO Belt Bag" and they never sold them on stores.
Only one of each color exists in the world and mine is this orange bag.
Please call Bean Pole to check if this is true. They'll tell you the same story.
