With just very slight modifications this "ID Holder RFID Blocking Slim Credit Card Stainless Steel Money Travel Men Wallet" that I bought on ebay is the perfect solution for storing your Trezor Bitcoin Hardware wallet. The Trezor comes with two cards for writing down your secret words. I suggest you put one of the cards in with the wallet with false words. This way if a thief takes your wallet they think they have everything they need but they really don't.
The only modification required is to remove the cardboard credit card organizer that comes with the case and then replace it with the cardboard you see in my video. Takes about 1 minute to cut the cardboard to size and use the existing glue to hold in place. Done!
