So the fastener is the thing that hold this all together. It's super cute, but that means the bottom of the envelope slits are not sealed. It's great for cards, but cannot hold change b/c of the slits.
It's also not as super small as described - to fit into super skinny jeans, that fastener sticks out quite a bit.
Overall it's cute, and the leather's great quality, but the slits make it not able to hold change, and the fastener sticks out too much.
