The packaging is currently under development. Of course every single Aviator Wallet will be shipped with a packaging. This will be also suitable for giving away. We will give You an update as soon as it is ready.
The back plate is securely held in space by the pressure of the elastic band. You can adjust the band to the amount of cards you want to carry by means of a 3-step-adjustment. This will automatically exert the right pressure for a perfect fit.
We only use the best available aluminum for our product, but we do not recommend not to wear keys in the same pocket as the Aviator Wallet: When metal rubs on metal, even the best aluminum is not 100% scratch-resistant.
