I have a TPU clear case for my redmi note 7. I think it really has good quality. My phone dropped three times, but my phone doesn't broken at all. I like it. You also can get one.
I have a custom clear case and think it is good.The design is printed on the back of the case and the sides keep the transparent colors. So if the case will become yellow, it just has the sides is yellow. I have the cases two months and now it's OK.
