Christmas trees, reindeer, bells , stockings - and a whole lot else besides: the Sony Xperia Z Christmas Case has got it all. If you want to add a splash of festive colour to your phone, look no further than this fun, original display. When it comes to protection though, this case is completely serious: it consists of a tough plastic shell, hard enough to protect your phone from knocks and drops, while allowing full access to the screen, ports and functions.
