I bought one of these for myself about a year ago... it's a great product.  I always am on the lookout for a slim wallet, not a standard wallet.  I've purchase items with built in money clips, only to never use the money clip... not to mention the money clip can be annoying rubbing your leg in your pocket.  This wallet has a few compartments and one of them can hold about 10 cards with ease... it does not specifically hold cash, but I fold my cash in half and keep it tucked inside the folded wallet.  The material is great and slowly stretches and opens up over time.  I just bought another one for my brother for his birthday after he admired mine.  It's really a great product.  Would buy again.
