How to Remove Security Tags From Underwear

He tried to open it with a very powerful magnet because we figured that was how it should be done. But when he went back to the same shop - Big W - he found out they've got a whole device which works like lock picking. 'I could go in there now with the undies on the receipt, and then they would take off the tag but I still would not know how that tag works,' says Becki.
