My favourite iPhone case all the way since the iPhone 5 has been the official leather cases that Apple sell at their stores and online.
I’ve gone through both saddle brown and black and have always been impressed. They’re made from genuine leather and patina so well over time. The more you use it the more character it gains.
The case protects against drops and scrapes very well and has saved me from a cracked screen countless times. It’s not bomb proof but is more than adequate for everyday use.
Many like to say Apple are expensive but I’ve yet to find a case that matches the Apple one in terms of fit, finish and design. Genuine leather cases are hard to do and they’re not cheap. Apple’s leather cases are actually very good value for money.
