I just wanted a metal case to keep my cigarettes in so that I could ration them.  Somehow for me it's easier to cut down on my smoking when I don't have a whole pack lying around.  The clasp is strong and the inside could easily hold a whole pack I'm thinking.  There's a metal arm that holds the cigs in.  I don't know if it would be the most secure for those of you looking for something to hold your business cards, but it works well for me.  The one small complaint I have is that the metal was a bit smudgy looking, and remains so even after I've polished it a little.

Overall I got what I wanted.
