    Perfect for me
    Color: Two Tone - Black/Grey
    I love it. Quality is great and I needed something that would comfortably hold 8 cards/ID's. This is slightly larger than my previous on but that one only held 4-5 cards. So, you know, the more you carry the larger it has to be. This was perfect for me. Oh, and the Magnet is perfect for the money. I love magnet money clips for their ease of use. The letter loosens up after about a week of using cash and allows it to hold many bills securely after that break in period (like good shoes).

    Nice small wallet, almost too small, ID pocket not very useful
    Color: Two Tone - Cobalt Blue
    It looks really nice and well-made, but the ID windowed pocket is too tight to easily get out your ID then you need to use it. No one lets you keep your ID in the wallet, so why bother with a clear window pocket?

    Lots of Space for a Small Bag
    Colorful and great! All Haven't been without a Coach bag since the early 1970s. I'm usually not fond of the signature bags, but this one is striking. Of course it is well made. The bag has two compartments that are large enough for checkbook & phone. It has 8 card holders, 2 smaller places for business & library cards, a place for folding money, a zipper middle compartment and 3 flat compartments for receipts, notes, etc that are all packed into a cool small bag. It comes with both a crossbody metal strap and a leather wrist strap.dd Often, I've found Coach credit card holders inside their bags are too small for credit cards. This bag has larger cardholders. Overall, I give it an A+.
