I used to use the paper sleeve protectors, but my cards were not securely held in the sleeve. This is secure and sturdy aluminum. I am able to fit 5 cards with embossing and 7 without embossing however, the manufacturer recommends 6. Fits in my front pocket comfortably and easy to find in my back pack or purse. Cards cascade as they eject. I have my NFC card at the back so that it comes out just far enough that the reader can still read the card. Great product for cards only. If you carry cash there is a money band accessory and wallets that are compatible and allow you to carry cash, receipts, etc.
