We have had brown folios for 5 plus years, they go a real patina, not just grime /dirt like apples leather patina used too.All the leather except a couple of cheap. But if you have anything other than black, you could see that Nomad doesn’t patina like the Apple cases did. You can call them cheap if you like, but Nomad is not high quality leather either.
Apple stopping making leather cases was nothing to do with being eco,
