See what style you like, the ultra-thin PP case is cheap and feels best, and then there is a leather phone case made of PU for about 50 yuan, and more than 100 for leather.

There are also two brands, UAG and EVUTEC, which are tightly packaged and well protected, and the price is slightly more expensive.
