I ordered this RFID-blocking billfold out of concern of having my cards "cloned" while still being in my pocket.
The wallet appears to be well-made, and for me it's impossible to know if It really offers the protection claimed.
The wallet is thicker than my regular, plain billfold, without the two plastic "windows" my regular wallet has. Being thicker, I will have to carry fewer items in my new wallet, or it will ruin the back pockets of my casual and dress trousers.
In any case, it was not too expensive........I guess I'll get used to it.
