like so many people seem to be saying about so many passport holders, this one is too small for a US passport. it's not so small that it can't be snapped closed with a passport in it, but it doesn't close evenly - the passport pushes the fold point off-center so that the edges of the holder don't meet evenly by about half an inch, making the holder look, well...like it's too small for its contents. the neat look of the holder was one of the reasons i bought it, and that's compromised by the holder's inadequate size. it'll probably still serve its RFID blocking function (i certainly hope so), but it won't do it quite as prettily and neatly as i'd hoped.

the choice of a snap closure isn't my ideal either - snaps take a little more of a deliberate effort to line up and snap shut than velcro, which can generally be fastened without looking. that said, as snaps go, the one on this holder is a good one and doesn't demand absolute precision in order to snap properly.

since writing this review i figured out that the passport holder is only too small if the whole passport is stuffed into the clear plastic window thing as shown in PacSafe's product photos on their website. if instead, the back cover of the passport is slid into the pocket behind the credit card slots, and the rest of the passport left free, the holder closes quite cleanly and evenly. this doesn't hold the passport very snug when the holder is open, but it lets the holder close properly. putting the passport's front cover into the clear plastic sleeve and the back cover behind the card slots will hold the passport quite tightly, but you're just going to have to remove the passport from the holder for security people to scan it anyway, and that's considerably more difficult with both covers tucked in that way.
