Hi~all MJ lovers~please help!! I have a problem with my stam chain strap... Not only did the chain lost its gloss (it is now in a dull.dark gold color)...there has been black stuff coming off of it... and it's making my white chiffon stam all dirty...:cry: the other metal parts(zipper, kiss lock..) still remains shiny gold... I bought this stam last year directly from MJ boutique... I suspect that it might be the oxidation of the metal... What should I do??!! Does anyone else have this problem?
