        Pen holder feature isn't good
        Color: Cocoa
        Edited review: previously I gave this a two-star review because when I inserted the pen into the pen holder the wallet couldn't close anymore... I tried taking it out putting it back in a few times and it seemed obvious to me that something was wrong and I just could not figure out why the wallet possibly was having an issue closing even though it's designed to hold a pen... To me it seemed obvious that when inserting the pen you should have the clip on the inside where are the bills go.... That single millimeter of space that that clip takes up in the bill fold causes the wallet to not be able to close properly so it springs open. Needless to say that felt extremely cheap for a product of this price and I was very unhappy and considering a return and after writing a bad review I happen to see product pictures with the clip on the inside of the wallet where your cards go and it dawned on me that I had just simply put the pen in in the wrong orientation. That completely solves the issue. So updated back to five stars, and the wallet is great. 2n update after using it for a week on an international trip so I was carrying my passport. Worked great - made me feel safe to always have my passport and room for all my most important documents inside a -just- large enough for a passport wallet. I really don't think they could have saved another millimeter and still made such a quality wallet. Having a micro pen in there is icing on the cake - makes you feel like James bond. I also felt safer having a hidden bill compartment so your not showing a fat stack of foreign currency (I mean depends on your use case but I was in some rather poor areas and this added some peace of mind and 'security' in my opinion). You can just keep some small bills up front and your real stack on the hidden flap. I won't dock a star for it - but keeping this on a back pocket so you're sitting on it because it's bigger and the way it holds cards after just one week there's already card imprints on the leather (just imagine your older leather wallets where the cards start wearing through the leather) Also I tested the RFD blocking and it indeed works. I'm unable to scan any cards through the wallet and that was an important feature to me. Even when the wallet is open and I ran scanners directly over cards (in the sleeves) it still didn't pick anything up.

        Works
        Color: Cocoa
        Good wallet that can fit a passport, hold cash, and cards. “Hidden” pockets too, but that just means more storage space to me. Soft and supple leather that gets better when conditioned and cared for properly. Main feature I like is the RFID blocking, I only get wallets that have it. Expensive- yes. Works, also yes.

        Really bad amazon customer service
        Color: Black
        The wallet seems great but the box it came in wasn't sealed. It was supposed to arrive by the 22nd and it arrived 4 days later. I needed it for a trip on the 1st. When I took it out, the wallet had two scratches at the back and the pen was also scratched. I contacted customer service and they couldn't help me in any way to get the replacement item before my departure date. I kept it anyways because of thr necessity. Gave it 3 stars because of the good quality of the wallet
