Review: Better Quality than expected - Got it as a gift for someone who's a physics undergrad student for VDay and he loved it. 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.
Review: great nerdy gift - got it for my nephew who’s about to go to college for physics and he absolutely loved it, great little gift for any physics nerds out there
