Great Hold-All
This seems to be well-made and I like the configuration. It should hold passport, ID, credit cards, cash and any travel docs with no problem. It is a bit larger than I expected, however, so that will have an impact on what sort of purse, belt bag, or etc. I use to carry it. My biggest issue with this and ANY RFID blocking wallets/purses/etc. is that I wish the manufacturers would add a sewn in tag or imprint on the product itself that SAYS it's RFID blocking. After time goes buy it gets hard to remember which items in your travel stash are or aren't. I've used a Sharpie to mark this one, but it would be nice if the manufacturer did so professionally.

The most complete, compact wallet I've ever seen!!
This is the most complete, compact wallet I have ever seen, there is a space for everything, even coins. I ordered 2, one for me and one for him. Mine does not fit in my purse, it's 10 inches long. I'm debating, should I return mine or keep it. I've searched for one similar, less than 10 inches, and found nothing. He is so excited and happy, he has already filled his up. This is the only wallet one needs AND it's RFID blocking.
