Not only are these cases super cute, but they're also protective. The back of the case is a hard PC (polycarbonate) plastic, while the bumper is a firm but flexible TPU (thermoplastic polyurethane). These materials maximize protection without bulkiness, so the case maintains a pretty slim profile. The iPhone mini's diminutive size actually makes many cases surprisingly hard to remove, which is a pet peeve of mine. But this case is easy to put on and take off. The edges are not slippery, so I feel I have a firm grip on my iPhone.
Wireless charging works just fine. This includes Apple's MagSafe charger, though you don't get quite the satisfying click that you do with a naked iPhone 12 or a MagSafe-specific case.
