Which Are The Most Expensive iPhone/iPad Cases?

Only if you want to keep your product in good condition.

There are iPhone cases that go in the thousand dollar range, but would you spend $2K for a case with diamonds on it? Rationally, I wouldn't.

No. I switch between an Apple bumper, and no case at all. I am a very careful person, so that's something to consider.

the most expensive one is my used one it's 100000£
