Using this wallet is a breeze. You can easily slide your cards into the multi - card slots for quick access when you need to pay. When you're done using it, just fold it up and put it in your bag. As for maintenance, remember to wipe it with a damp cloth whenever it gets dirty. But don't leave it out in the sun, as that can damage the material. Also, since it's made on demand, you can order as many or as few as you like according to your needs.
