Nexus 6P detachable wallet case

Is there wallet case that has detachable shell?
I mean like Spigen snap leather wallet (can't post links to images [emoji53]).

Wallet Folio Case

Does anyone know if there is a good wallet folio case that exists for the 6P? Looking for a higher end case possibly leather. Something like this looks nice to me - doesn't have to look like a book though.
