Exactly what I needed for traveling!
This Amazon Basics Travel Passport Wallet Organizer is amazing value for the price. It has multiple easily accessible slots & pockets that can be used for credit cards, boarding passes, receipts, pens, and currencies if traveling internationally. The wallet has a zipper which can safely secure folded documents such as immunization records, marriage certificates, and citizen forms if needed. The functional design is larger than I anticipated and the material feels well-made, solid, and looks nice. I could not fit the wallet in my pocket, but it easily fits into a backpack or purse. If I happen lose this or misplaced this one, I will be purchasing this again.

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.
