Preloved Vintage Givenchy Brown Shoulder Bag,was told it was authentic.

Preloved Vintage Givenchy Brown Shoulder Bag,was told it was authentic through Poshmark support when I was questioning it,but also said to be sure, I could always get a third party authenticator if I wanted to, which I have not done.Bought from a store in Cali that is known for authenticity ,but through their Poshmark .The outside pocket is severely stained on the bottom with some hardened black material .Does not flake off and doesn’t seem sticky …just hard.Still useable.You cannot feel the hardness from inside of purse.Inside is perfect .Outside flap of purse on top of Givenchy logo does have some spots of some paint,peeling, or nail polish..haven’t attempted to get it off,so unsure if it will come off or not.Callouts and not knowing true authenticity are why price is low.I like to be transparent.Height - 9.5 Inches,Length-10.5inches,Width-2.5 inches
