Bring the hammer down on Black Skull and his goons with this Harley Quinn Birds of Prey Mallet. Harley’s favorite time of the day is hammer time so anyone dressing up like her will need this prop. It has a long black handle with a red and white diamond pattern on the head. There is a knocked out face printed on the side because that is exactly what happens when she smashes someone. Carry this around while wearing a Harley Quinn costume for the full effect.
