Welcome!
I don't know if it's the same model that you are considering, but for what it's worth, I have an intrecciato nappa key case in violet from a few years ago. I have the kind that folds shut with a snap, with key rings dangling from a bar at one end (there are two sizes of this, and I have the smaller one).
I think it's held up really well, but then again, I don't have any expectation that it would stay new-looking, either. It has a few dents and scratches on the smooth non-woven interior, but it doesn't bother me at all. I'm sure if I studied it, I'd find some evidence of rubbing on the outside, but nothing I notice on a daily basis. Also, I don't keep it in a coat pocket, so your usage may vary. Mine stays mostly inside its own pocket in a purse organizer, but sometimes it's loose inside my bag with the other contents. Hope this helps a little bit!
