STARIM Minimalist Carbon Fiber Slim Credit Card Case Holder Wallet & RFID Blocking Front Pocket Money Clip Ruler Style

Very difficult to get cards in and out - the edges of the carbon fiber are not beveled at all (I was able to file the edges and make improvements there). The CF is not slippery like aluminum making this worse. I tested the RFID with an access badge and it didn't prevent it from working. So I'm not sure why they claim any RFID blocking.
