I just got a Kooba Meredith bag in Slate Grey, which I luv. It's made from super soft lambskin. Apparently, some bags are a little more inconsistent than others (as indicated on the Kooba tag), but I don't think it diminishes the bag's beauty at all. (the first pic is a stock photo, the 2nd is my bag).
I think there are other styles available in this same color.
