i need help, i returned my manhattan pm because after a month from my purchase, i found black spots on the gold metal hardware, the SA said its a defective item. She gave me a credit note and i have the choice if i will get a new manhattan pm or another bag. I think the gold brass metal on it will give me a hard time in the future having tarnish and all.what do you guys think?I'm thinking of the neo speedy denim, baggy pm in green, mono batignolles H and speedy damier azur.help.help. help! can't decide..-Thanks
