This is a brand new official stock Xbox One controller customised by Custom Controllers UK with no mods installed but you could use the case on a controller if you have one that might already have the mods, it just looks to good not to have, even if you just use it a stock controller. This controller is surely going to make all your friends want one as well and we have plenty of different colour combos to choose from. All you need is to add batteries and away you go, oh and did we say the batteries are included as well with this controller! Custom Hydro Dipped Painted Xbox One Money Design
