These cards are engraved with “fricken laser beams” and are anodized aluminum. Typical engraved Miranda cards are made using flimsy, thin, cheap aluminum but ours are thick as a bowl of oatmeal and sturdy. The Extract-ED Miranda card is a better product, for a lower price, compared to Amazon.  Extract-ED is a police-owned small business and profits from these cards support law enforcement training.
