You might check out the a Peel cases as well. They have 2 clear cases, one soft and one about the thickness of wax paper. I have the soft one, which is almost perfect except the buttons are stiff. My OCD is driving me crazy with the clear cases and getting tiny little particles between the phone and the case that I can see of course.
I settled on the hard clear case since it looked thinner than the soft clear case. I got a 15% off code for signing up for their emails. It look thinner than the Spigen Liquid Crystal case which slippery and hurt my hand when texting because of how thick the case is. I even sent my Apple silicon case back because it’s too slippery for me. The size was perfect besides how slippery it felt. I guess I really just wanted a clear case to show off the pacific blue.
