How big is it? Well, here's a comparison next to a standard US dollar bill:

And here is the really clever bit: it has these little fabric dividers that are cut in such a way that you can organize your cash and cards and such to easily get to them... with a clear face for the front section. I tried to get two pics to show the design below with some actual stuff so you can see it:

And finally, a shot of the wallet clipped on the snap hook on my Brain Bag's front compartment!

Once again I am amazed at how Tom & Co. can take a relatively simple idea and, with a few subtle design enhancements, transform it into something special. This is exactly the right size to hold some cash, some credit cards, and your ID or business cards. The dividers, besides protecting your credit cards from scratches, allow for quick and easy access to the compartments with the alternate tab design. And the addition of the clip allows you to quickly snap it in and out of your bag as needed.
