I was comparing the chains on my classic flap and my woc and they seemed to be different. The chain on the classic is a lot lighter in weight and in the gold hardware color. It's almost plasticky!? The woc is a lot heavier and the gold hardware is brighter. I know they're real since the classic was bought at a chanel boutique and the woc was from chanel at saks. They were bought less than a year apart. Does anyone else notice this with their bags?
