I searched all over for these simple passport covers, ever since I warped my passport in the humid heat of the Philippines last year. Oddly, none of the airport stores carry these. Go in on the 5 pack with your family and friends. One thing - in many cases, you will have to remove the ID page of the passport from this plastic holder in order that it can be read by the electronic security instruments - nevertheless, this protective cover is still great to have.
