This necklace was custom made for the production for use by Scarlett Johansson as "Black Widow". The necklace features a design that was seen in other props also made for the character "Black Widow". It was thought to be used as an concealed weapon or an explosive device, however the necklace is not seen in the final cut of the film and may have been used in a deleted scene. The necklace is presented on a custom acrylic wall mount display. This item comes with a studio sanctioned Propworx COA and was marked by the production as a hero necklace.
