I just received this wallet, and it is much larger than I was led to believe from the product description.  It is actually tri-fold, not bi-fold, and is more than 10 1/2 inches long when open.  It has a zipper pocket and TWO mesh card pockets, plus the billfold.  It's a nice wallet, but I intended it for my 2 year old, and it's about as big as my husband's full-size wallet.  It's definitely not able to fit into my son's pocket.
