I have the grey version of this bag, which I love. But I can't tell if this is authentic. Your assistance is appreciated!

I'm still selling off some of the excess stuff I keep buying! 
The bag looks good, but a quick peek at the seller's feedback might turn off a prospective buyer.
I want to make a point about the importance of looking at the feedback and the possible reason behind it, but in this case, the seller (IMO) got a raw deal.
The buyer negged the seller because the bag was scratched, hardware was scratched and shipping was "slow."
1. The buyer purchased a used bag and it was described as having been carried, thus there is apt to be some indications of use
2. The leather is burnished leather and is designed to scratch. It's the nature of the leather and is NOT a flaw.
3. Buyer was unhappy with perceived slow shipping. Buyer opted for the seller's free shipping option, which was probably parcel post. The buyer received the item within a week of purchasing it -- not bad for parcel post.
My point is that not all negative feedbacks are the seller's fault. I think the seller's assessment of "buyer remorse" is accurate. (In fact, I've blocked this buyer. She seems impossible to please:

JMHO.
Again, the bag being questioned looks fine.
