Nice quality leather wallet, lots of places to put IDs and credit cards. I'll take it that it is RFID blocking, no way of testing that!! If you like to keep photos and other IDs in the clear plastic windows, you'll need to buy those separately. Still, this is a nice wallet, good quality, holds my "stuff" -- I'm happy!

Outstanding Wallet

Very good Wallet Nice leather looks very nice and was easy to break in. I carry it in my front pocket and it is not to bulky. Holds a lot of card and has two pockets for cash.
