This wallet is larger than I expected, but I didn't know that a phone really could fit in the pocket behind the bottom half-my iphone 7 with an otterbox fits in there! For a slim wallet, it's not too slim, but because it holds a large phone it gets 5 stars. It's well made and has the perfect amount of pockets for me. I'm not sure how to test if it's actually RFID but that brings me peace of mind.
