Not only did the zupper pull spatter off, but so did the little triangely thing that certainly zips the two sides together, so all that's moved out is the jaggedy siding. I don't have the triangely zipper thing any more. This is my favorite jacket and I really want it fixed, HELP!
Where does this Beep nouns come from?
