Expansion unfortunately impossible

In itself, a very tailored sleeve. The problem I had with the thing, was the "expansion" of the RPI's.
The Pi can be, unfortunately, without the housing to break, no longer be removed from the case. I tried it almost hours.
I hope for the producer that it was not because of my disability and I'm doing someone wrong here.

But must never take for people who your Pi again from the package a good low-cost envelope.
