I use one that is molded and holds 2-3 credit cards on the back. That's all I need when I go out. No more drivers license to worry about but makes it more difficult to buy booze even with my gray hair.

Otter box hands down only way to go I tried out cases nothing like a otter box defender sorry everything else is shit!

I use one made by Torras which has a way to attach a lanyard feels great in my hands but may be considered boring. Has good bumpers on the sides for protection too. iPhone 12 mini user here.
Get a case that functions well, then customise it with stickers or feely things etc.. I need to take my own advice here I think.

I recently got a Loopy case after having an Otterbox and pop socket for years and I’m really pleased with it. The case seems to protect my phone well without being bulky and I haven’t dropped my phone at all since using this case.
