The cost of the case is 6 which comes in a decent raspberry and white colour design.
It is crafted from injection moulded plastic which neatly fits the Raspberry Pi 2 Model B and Model B+.
We spent months refining the design until we got to a point where we thought to construct.
The case we are selling today was as good as a case probably could be, Hollingworth added.
So the conclusion is that it is not just a plastic.
