I bought this as a gift for my dad this Christmas. He asked for the thinnest wallet possible, but sturdy enough to last.
Unfortunately, in the world of wallets, you can't have both. You either get a huge, bulky sturdy wallet, or a flimsy piece
of junk.

This money clip is the closest thing I've found to a thin/sturdy compromise. It is INSANELY thin, when empty. The metal
spring clip seems solid, and it's genuine leather. It does bulk up the tiniest bit once you put a few cards in it, but it still
maintains a very thin overall size.

I can't say it has withstood the test of time since it hasn't been put to use, but I think it will prove itself a decent, ultra-thin
wallet. For $11, if it only lasts a year or two, it will be a worthy purchase.
