I bought this one and it came 2 days earlier than expected.
It is nice size, small, fits nicely in the back pocket of my jeans.
I did have a problem with the achordion style, it does not allow for many credit cards but you can remove it without damaging the product, however i made it work, also the width, it's thicker than i would like.
Overall im very pleased with this product. I would recoment it =]
