Great news! Evidently my grey Chanel didn't need long / much effort to touch up. Leather Surgeons just sent me the invoice and it will ship back to me tomorrow.
I was hopeful it wouldn't need much work. The structure and leather were perfect and there was no scuffing or scratches to the hardware. It just had the weird scuffs on the top of the bag (how the heck do you scuff the top of a bag??) that were worrisome.
I see me getting a LOT of use out of this bag! I'll post photos when she arrives. Ohmigoodness, I can't wait!
