Thought I was buying authentic, and found all these reviews after mine was delivered. Spent hours checking my YSL bag against my other real one from the real YSL store and it was definitely fake. The background colour behind the gold Yves Saint Laurent writing on the tassel is pure black on the cosette one, where the real one is a lighter stained black. Also different shaped zipper and could tell the gold hardware was cheap not the same quality as my other YSL store bought bag. The tassel weight was very light too in comparison to the real one which was heavier. Don't be fooled these are just very good fakes! Such a shame so disappointed but most of all, Shame on this company that is charging "authentic" prices for counterfeit products!
