Exactly as advertised, as far as size goes. The make up for the width by placing cards edge to edge, instead of stacking.

Pros:
- fits 16 cards, as advertised.
- thin design, simple and clean
- leather flaps to hold cards in
- fits in standard adult back pockets with no issue.

Cons:
- to get 16 cards, you have to put two cards back to back - as in, there's only 8 slots, that are 'wide enough' for 2 cards.
- the cards slide ALL the way into the card slots, making it difficult to get them out
- when a single card is out, the 'companion' card in the same slot is loose, and falls out.
