Much easier than cramming all your rarely used cards into a giant wallet. Now I can place all 3rd party cards, gift cards, loyalty cards, business cards and punch cards in one place. So if it's not in my wallet I can find it here. You can also take it out of your wallet and leave it at home when you don't need it. Now it has 40 cards. Please note that the cards are a combination of credit, gift, business and paper loyalty/punch cards. The wallet is not completely filled, there are 1-2 slots left, but some cards have doubled. Both the front and rear slots have multiple cards
