Nomad leather cases Patina really well, been a Nomad user for many years - their leather is less delicate compared to Apple's leather case.

I currently own the Leather Case for iPhone 13 Pro Max and upon holding it for the first time, I can already tell that this leather will not last - just by holding it you can feel some moisture from your hands seeping into the leather

Never had the same issue with Nomad's cases - the only downside with Nomad is the thick-@ss bumper vs Apple's slim profile.

Its the Modern Leather Case, as long as its made from their Horween leather range, you'll be good.
