Unfortunately, only short-lived

As such, the shell is nice and fits very well to the iPad Air2. Unfortunately broke after only a few weeks before the first plastic pieces on the corners of the envelope back from. The material is simply too thin.
It's a pity the otherwise I was very pleased with the look and feel of the shell. But a life expectancy of just 3 months is simply too low.
And to prove that the envelope was not damaged by improper use (crash ..), is unlikely to be possible.
