This sportcase is made of real leather. The structure of the case consists of a hard plastic case covered in soft leather. This leads to a slim and stiff fit, the case does not feel bulky, light and provides a decent level of protection.
The sides and the inside of the case are covered with suede that gives the case a smooth and durable surface. That would not scratch your phone at all!
The case fits very stiffly and does not scratch the iPhone when installing or removing the case.
