Alexander McQueen The Knuckle Twisted Leather and Silver-Tone Messenger Bag
From MR PORTER
The knuckle dusters on Alexander McQueen's 'Twisted' messenger bag have been a signature since the brand's early days, each one is expertly carved to resemble a ring. It's been made in Italy from black leather and comes with a detachable strap, so you can carry it in hand or cross-body.
