I received this shell for testing and could also compare with a model Nubuck this. A similar version of this type of leather is also available from this envelope, this is but a corner expensive. In my opinion, the nubuck feel due to its soft texture to better than the rough Nappa leather. A big plus of the nappa leather is the black version, the simple design that goes very well with this point very restrained Sony Smartphones. On a great logo is omitted here. Fits especially for a black Z3.
Conclusion: You get here a good cover to protect his faithful companion not only against scratches, but also to reduce potential damage from accidental dropping. In addition to the many cheap plastic or leatherette cases this model is convincing in particular.
