I bought this wallet online with the leather case accessory. They were both a complete waste of money. The interchangeable plates were a pain to remove from the slots, and the wallet, itself, did not seem very durable, so I wouldn't recommend putting it in your back wallet unless you dont mind switching it to your front pocket every time you sit down. I never realized this until I began installing my cards into the wallet, but not all credit cards have the same dimensions. This can make a big difference in the way the wallet performs. One of my credit cards is around 1/4 thinner than the rest. As a result, this card would accidentally slide out of its slot when I moved the wallet, or would remain in the slot even after I pressed the lever to push it out. To make things worse, I already paid for the leather cover. I bought the cover to place my cash and an extra credit card inside of as advertised, but the pouch included is not large enough to fit a standard card, and the cash sleeve is not capable of holding more than four bills! You can try using the clip attached to the wallet for your money, but I wouldn't trust its resiliency to keep the cash in place.
