Good-bye Cardboard, Hello Stainless Steel

I can carry a lot of paper money in there, no one is going to break in (from the back anyway).
Hey Dibbons,
Looks great!
Suggestion: Line the inside with felt board, available at any craft store. Its about 2/32nd thick, very durable and, it will give you a stock look with the aluminum strength. Also, no rattles and everything put in there won't slide around making noise.
