This is the distressed ombre calfskin from 2013 and it looks like it may be the brown color, but I can't tell from the photos. It came in grey, brown and green. It is limited edition and as the name suggests, it is calfskin leather.
Thanks so much Saira. I screenshot your post so I will remember lol. I'm disappointed its calfskin, was hoping its chèvre because I keep hearing members saying how great chèvre leather are! Oh well I guess that gives me a good excuse to buy more Bal bags. Again....thanks!
