Announced in May 2012, Factory Entertainments' Neuralyzer prop replica is crafted with exact precision as it's seen in the Men In Black II film. The Neuralyzer was used throughout the Men In Black II film to have characters on the receiving end forget prior events and have either K (Tommy Lee Jones) or J (Will Smith) iterate preferred events back to the character. Limited to only 1,500 pieces worldwide, the Neuralyzer went up for pre-order in May 2012 and began shipping in June 2012.
