The case isn't set up for business cards, they will not fit inside. It is more for credit cards. Had to cut the interior according pockets out to allow room for business cards to fit
Merchant Response:We're so sorry you're having this trouble. Our standard business cards do fit in, a little bit snugly, but they do fit. If your's don't fit (there may be slight differences in card size), we'd be happy to send you a different card case free of charge. Just email us at firstname.lastname@example.org and let us know which case you would like instead. Sorry again!
