Design and size are perfect. Very thin and seems to last a while. As for RFID blocking, it doesn't seem to be 100% effective, but it works to a degree. I tried using the RFID company ID card in the wallet and the ID card reader on the front door was still able to read it. However, all internal card readers will not read the card unless it is removed from the wallet. Maybe it's just a special reader at the front door. So this gives some level of RFID blocking, but not 100%.
