Make your own with padding cement. Put the stack of bills in a vice and coat one edge a few times with the cement. I did this for a nephew as a unique gift. Some people being paid with these are suspicious.
Nowhere near as suspicious as the tire shop in east LA late at night on Sunday when I needed a flat patched, and I only had credit cards on me - and a uncut roll of $2s in the trunk.
I pulled that out to cut some off and pay and they all started screaming about feds and told me to get the hell out of there, no need to pay.
