Although I havent bought anything from this seller but I had a look at her feedback and it's very good. She has users expressing authenticty on her purses she sells.
I had a look at the Chanel bag she has listed and looks authentic. The stitching is done what u should expect & align with perfection at the back with the pockets. The CC is done well and correct. The inside looks as u any Chanel bag got. Also the auth tab inside is done well and corresponds with the hologram card.
