If you are looking for a card holder to store your credit cards, then this card holder from Holdit is sure to be a hit. This MagSafe compatible card holder fits both MagSafe compatible devices and cases (also works with a large number of magnetic cases, eg Ideal of Sweden). But also works for all other phones and cases if the included magnet is attached (leaves no residue)

The card holder is made of high-quality vegan leather, which gives the card holder a long life. The card holder holds 2-3 cards while remaining super thin.

Apple MagSafe Compatible
The card holder has a built-in magnet, which means that all MagSafe-compatible devices will automatically place the card holder in the best place on the back of the mobile phone. The card holder will also work similarly with MagSafe compatible cases.
