Review on 👝 The Latcher Minimalist Wallet & Card Case Companion: Sleek Synthetic Canvas Leather Wallet for Simplicity and Style by Kristi Hovde

Probably fine as a simple money clip, but not very practical as an addition to a wallet extension in a phone case. Basically it can only hold two cards and your phone case slots become useless allowing the money clip to fit in the phone case. And if you invest a lot of money, the magnet won't hold very tight. I do not recommend it as an add-on to a phone case. And I don't use it as a money clip (so I wouldn't buy it again).
