The shell itself or its concept is good. Case has been supplied with surface damage to the vinyl. But if ddie envelope when you first load already dissolves (see image), can be assumed this will not last long (if one can speak of durability). Furthermore, the seller is shipping in the amount of 2.75 EUR in the range of, but at the box office these 4.74 EUR. Better a manufacturer other than this shell choose dubious shipping information.
