I have the Alexandra and I LOVE it! I also have the regular Zippy Wallet, Curieuse Wallet, and the Insolite Organizer.
The Alexandra is my favorite. It holds the most # of credit card slots and it has a window for a Drivers License. I bought a leather strap and attached it to the coin zip and can use it as a handheld when I have to rush out. This wallet can hold a lot more than it looks considering it is smaller than the rest.
I think the Alexandra is very under-rated.
