Rigid plastic shell that covers your Xperia M (C1905 or C1904). It fits perfectly and stays in place. The function keys, the speakers and the objective of the NPC are available, just the one that triggers the camera where you have to press a little harder.
One small problem: cutting the micro USB connector level could have been a thousandth of a millimeter wider: the charger does not fit fully and tends to come off as soon as you move the camera. But this is not very troublesome.
