Like the description, it's even thinner than it looks in the photo
100% Carbon Fiber Credit Card Holder
The product is as detailed in the description. I can't prove it's real carbon fiber or not, but I can say it's not technology. RFID talking about, I checked with several cards. For me it is the best finish this product has. I bought the metallic finish too and I find it very heavy compared to part of the sound they make the plates between if I don't like it. One thing to highlight is that the rubber bands you're wearing are given of yes, you'll have to trade them for the ones he's bringing back. One point in favor of rubber rings is that you can replace them with any of a hardware store. The shipment was very fast, a great point in favor since it took much less time to arrive than they said.
