First has wondered why the hard part of the casing was slightly curved inwards.
The soft part is loose bissl.
But the bigger problem was the hard shell!
The hard shell has not been pinched by the slight curvature on the sides of the I phones. Thus, the hard shell has had absolutely no maintenance and can thus easily solved.
Thus, the part went right back!
If the purpose is not met with me and can thus also make no recommendation to buy.
