I have carried this wallet since my chiropractor told me a decade ago that I needed to carry a very small purse into which I could not stuff lots of things. (I had always gone to bigger & bigger purses to fit additional things that I felt were a necessity for me to carry with me all the time; I have since set that large purse aside as a "day bag" that goes with me only when I travel & in which I can actually store this Buxton String Along wallet to consolidate.)

It fits a checkbook, allows credit cards to be lined up so as not to have magnetic strips demagnetizing each other (which happens when the magnetic strips actually overlap each other), has room for plenty of other small things and coins, a little slide-in pocket for a spare key, a zip pouch for whatever you want to store there (I keep non-magnetic cards there), and pouches on either side of the wallet on the outside (which are convenient for coupons or a list or whatever you need to deal with today.

The only warnings I will give are
1) Do not let papers or receipts inside get caught in the zipper when closing as it is very difficult to work the zipper when paper is stuck in it.
2) Sometimes the pen clip gets caught in the zipper, again, making it very difficult to open or close. I turn the pen clip so that it is not facing the zipper & haven't had any problems with it since (you just have to get into the habit of doing it). This one seems a little bit taller (perhaps by as much as 3/8" or so) & doesn't seem to have as much problem with the pen clip. I also don't use the pen that came with it but rather a different & better one.

I was so frustrated when our local stores stopped carrying the Buxton String Alongs...much relieved to discover them on Amazon.
