Dear reader, I use 2 credit, 2 business and 2 personal cards that fit perfectly in the holder. On both sides in the leather part, I use 1 ID and the other side my drivers license. The leather feels strong, same as the cardholder. All cards are of the same size. The logo and the print with "American Made" are an extra for me as a European. Too bad I had to pay about 35 euro import tax, but still it was worth to me. In the picture I uploaded in this review I went from my old cardholder to the Grip6. As you can see it's not merely an upgrade, but a whole other level! I love my Grip6 ! Regards, Wim
