This is a gorgeous triquilt YSL bag in perfect condition. Seems to be a caviar leather and very sturdy, no damage to chain or strap. Super cute, strap doubles to wear as an arm bag and can also be used as a crossbody. I am not an authenticator and I do not see a label or serial number on the inside, but this bag is gorgeous and great quality regardless. I got a ton of compliments when I used this bag! I am only selling because I only use gold hardware bags now and this is no longer getting any use. Open to offers or bundles with some of my other items.
