I have a concern there's too much shine and the bag isn't soft to the touch. I have other leather bags and lambskin leather jackets but this feels more stiff.
Hello, i really don't see anything wrong with your bag. I must say that since, & starting from S/S2012, Balenciaga use more gloss to treat the bag & the quality was not as good since. Personally, i'm not a fan of those from 2012 (im only talking about the moto range).
I ve owned Balenciaga bags from 2001 till 2015, just to feel the leather, study the features, tohelp in my authentication. Thus, if you are feeling uneasy about the leather as it's different from your 2006, i must say it's perfectly normal.
You can always go for paid service if you feel better![]()
Stefanie, for what it's worth I agree with PeaceBabe.

Your bag looks genuine to me for a newer Bal model, gloss and all. Many of the details with your bag are quite normal for the newer styles- 2012 & forward.

You can always get paid authentication as PeaceBabe mentioned. It's affordable $7-$10. or so. Authenticate4U is very good.
