This is exactly what I was looking for. My back gave me problems if I sat on a fat wallet all day. It's strong enough to only hold one bill, but easily fits $1,000 in cash. I bought some RFID blocking sleeves to use for cards as it is not RFID blocking. The money clips that blocked RFID were basically just another wallet with money on the outside, which I find stupid.
