I got a Tiffany one.

I was also gifted one that is just a large silver paperclip which isn't too bad but it doesn't hold that many bills.
Honestly don't use it much, I prefer using a card holder and just folding my money. I sometimes use a Comme De Garcons front pocket wallet that holds cards and money nicely and has a slim profile. http://www.mrporter.com/product/409758
