I purchased this set for my daughter to use for pretend play while we are studying about community helpers. She loved showing it off to her uncle who is a LEO (law enforcement officer) over their latest Facetime call. The handcuffs where broken when we received it but we were able to replace the broken jump ring to attach them back together again. The cuffs came with keys but they are really not needed to open them which is a good thing in case the keys were to get lost. The cuffs and badge are made of metal. The badge feels like a real badge and the leather case is awesome. She can wear it around her neck using the case and chain or she can remove the badge and use the belt clip to clip it to her pocket. She loves this playset and is proud to be a member of the special police department.
