Hi there, sorry, the New MagEZ Case Pro is not suitable with iPhone 12 Pro Max. iPhone 12 Pro Max is a little thinner than iPhone 13 Pro Max (7.4mm VS 7.65mm). Besides, there are subtle structural differences between the two models in terms of the camera and the buttons. So the New Pro can’t fit the iPhone 12 perfectly.
We already have the protective MagEZ Case Pro 2 for iPhone 12 Pro Max. Why do you want to put 12 Pro Max in the New MagEZ Pro? Do you prefer the design of the latter?
