Bonjour, for me the LUDLOW is too narrow. I've bought one in Paris years ago, one month later I sold it on Ebay, you can't put anything in this wallet !
The ludlow is a nice wallet to use if you have to just run out of the house quickly to do some errands. It'll fit in a back pocket perfectly. You can fit a couple of bills inside it if you fold it as well as a couple credit cards.
I use my ludlow to store my drivers license and my atm card. I mainly use it for my smaller purses. Its not practical for everyday use. But I love it nonetheless.
I put cash in my ludlow. I just fold it in half and stick it in one of the credit card slots. I carry my license, my credit card, cash, and a couple of other cards in it.
I love my Ludlow since I travel really lightly on a day to day basis. I fold my cash in half once & put it sideways in the coin compartment, it can fit quite a few too!
