Oh i totally see the difference! Thank you for pointing that out, I really would have never known! Thats crazy how observant you areAlso, I confronted the seller about my concerns and she said:
"Hi, I have two of the same bags, they are identical in style and size. I did not notice a difference in pebbling of the inside zipper pocket. My bags are older models...I always stuff the bags for photos so you can see the shape. I notice online when celebs wear this bag it is very limp and slouchy. I never deal with replicas, I hate fakes! I'm glad you like the bag. I love this bag. I had two for sale and I own various wang bags"
So I really hope shes being honest with me, but still wish I received the bag in her photo since it looks nicer![]()
The older bags are slouchier compared to the newer version. The newer rocco leather is stiff. Also, I think the small pebbles means thinner leather. JMHO.

I'm extremely picky about my pebbles, and since I've been authenticating, I know many sellers recycle photos from one bag. I've learned to ask sellers if the bag for sale is the bag in the photos.
IMO, sellers should photograph each bag because the pebbles are unique to each bag. It's not a good idea to use recycled photos when selling used bags. The seller needs to disclose the condition of every used bag, because they all wear differently. It's dishonest, and leaves the seller open to SNAD case.
Based on the photos you posted of the bag you received, the bag is authentic.
