This hermes birkin bag patternis an authentic CHANEL Chevron Quilted Mini Square Flap in Dark Pink. 
I purchased this in pristine condition from a luxury consignment store, Opulent Habits. It's well kept and I've only worn this ONCE since I bought it; therefore, there are no visible signs of use. It's in immaculate condition! The plastic on the zipper inside is still intact.  There's probably hairline scratches on the hardware but not visible to the naked eye. 
The chic cross-body is finely crafted of luxurious dark pink chevron-quilted caviar leather. The bag features a leather-threaded gold chain-link shoulder strap and a matching gold classic CC turn-lock on the crossover flap. This opens the bag to a smooth dark pink leather interior with zipper and patch pockets.
The bag comes with its original dust bag, Chanel box and Certificate of Authenticity from Entrupy.
