The packaging is in order and consists of a film with label printing and a way they need to use to open without scissors. So you could easily see the Case. The shipment was carried out in a padded envelope, which is perfectly adequate.
The case itself is made of a hard plastic cover (below) and a plastic / PVC (?) Coated cardboard. The plastic smell accordingly. The Z1 fits in perfectly in the cover and all connections are good but not optimal to achieve. In relation to the price but OK. For the magnetic connectors, the case must be opened.
What's not so suits me the previously mentioned, too short "hinge piece", which ensures by too high a voltage (a little too short), that the cover does not lie, but slightly apart. This error could have been avoided despite the low price through a better dimension.
Otherwise, this case is a good transition until you find something better. The material corresponds to the price and is certainly no comparison with high-quality plastics or even leather cases.
As I said, for almost 6 it is OK but nothing for the duration!
