Speck iPhone Wallet MagSafe Accessory - Removable ClickLock No-Slip Interlock - Holds 1-3 Cards - Soft Touch Finish, Scratch Resistant Card Holder Built for MagSafe - Black

I won't recommend if you are looking for a 1 card case solution, not able to hold the card at all..

Good quality with a strong magnet. Able to keep my cards on the back of my phone without worrying if it will fall off. Sleek style blends with the phone perfectly.

Great magnet. Wish it held at least one more card. Would def buy again.

This is the first MagSafe Wallet that’s strong and doesn’t come off easily. The ClickLock system delivers on its promise by securing the wallet better to the cover, and the magnet also seems stronger. I bought a cover in the same color, and just like it, the wallet doesn’t scratch. Another benefit is using MagSafe for charging in the car by removing the wallet. Highly recommended to everyone!

Permanently damages the cards. All my cards are now scratched :(. Other than that, magnets are on the strong side and you can fit 3 cards without any issue. Still I would not recommend it considering that damages the cards.
