This lovely object of pain was created by none other than Alexander McQueen. Yes I will take a punch in the face with this, might as well do it in style. Not sure where this can be purchased as it is no longer featured in the online store.
Found on RD Jour
This little tyrant was created by Alexander McQueen, the skull master. Skull ring created from silver tone brass with onyx horns, Swarovski eyes and a fricken mowhawk. Expect to pay $280 if you can find it as there are no store links where I found this on The Frisky.
