It has zipper pocket on top instead of on the side - it means bigger hole and easier way o add/remove items.
Still fits up to 3 cards per slot (it has 3 card slots), folded cash, and it´s perfect for your basic needs.
It has 1 ID window.
You can also insert it into your big wallet and use whenever you need.
