He couldn't wait to get it in his wallet. It is in fact, metal. I was expecting a thin piece of metal, that it would bend or snap easy but it's actually pretty sturdy. I was a bit worried about the size being too big for his wallet but it fit perfectly. The text is a bit small, but there's a lot of information crammed on both sides.
