This is my second one. It a great way to keep your cc organized. It also forces one not to have tons of stuff in your wallet while having the RFID protection. The accordion type card configuration makes it really easy to find your ccards.
I bought one for my wife and she wasn't sure if she'd like it. Well she loves it. I'm seeing more and more of these wallets being used. We travel a lot and these wallets are priceless. I have found the Shell-D's to be the best ones to buy. I have used other brands that were 3 and 4 times the price and didn't have the same quality as these. You won't go wrong with Shell-D's.
