The Mi 13 Pro ceramic and plain leather cases are generally not universal. Since the material and size of ceramic phones may be different from that of plain leather phones, their external dimensions and slot locations may vary. Generally speaking, for mobile phone cases of different materials, you need to choose a special mobile phone case that fits your own mobile phone model and material to properly install and use. It is recommended that you carefully review the product description when purchasing a phone case to ensure that it is suitable for your phone model and material.
