Bought to carry a few cards with me rather than carry a full wallet. The slimmer design is much better for back alignment. Holds 6 cards and has a central cash/miscellaneous compartment. - EDIT - New version holds 4 cards instead of 6 - still a great wallet. The corners are already starting to bend (I've been using it for 1 week so far). I think it may be 2-3 months before I have to buy a new one.
