This is already my third mobile phone where I use this case by Mumbi. And as always, the processing, size and function is perfect. That's all there really is not to say. Oh yes, the Sony Xperia Z1 Compact fits well (albeit with a little more effort), together with the Terrapin Hardskin shell into the case. The case expands with time and the phone + Hardskin fits perfect now. Absolute buy recommendation!
