Thin but expensive This one comes straight from Apple. It fits snugly over the volume buttons, side button, and curves of iPhone 12 Pro Max without adding bulk and feels great in the hand. Our personal favorite is the Totallee thin iPhone 12 Pro Max case. It is one of the thinnest cases around as it measures only 0.02-inch in thickness. Hence, it adds nearly no bulk to your phone while maintaining its original beauty. It is one of my favorites since you won’t feel you have a case on your phone, but it will still be protected from scratches and minor drops. Moreover, the company is so proud of its product that it offers a 30-day money-back guarantee.
