The zipper pull on my monogram papillon 26 has become discolored/chipped and I think my bag deserves a nice new shiny one. How much does it cost to replace and can they do it in-store or will it have to be sent somewhere? I should be more careful with my purses, but I'm usually a bit careless with them. I mean, I did buy them to get full use out of them! My papillon has even survived a mosh pit at a concert with me.
