This passport wallet is very nice quality, and seems to be well made.  My passport (about 4 years old) has a thinner cover, and flexes easily to fit into this holder.  However, I just received my child's passport recently, which has the new RFID technology.  Because of the computer chip in it, the covers are much thicker and not flexible at all.  You can put either the left or right side of the passport into the wallet, but not both sides.  So, the wallet still works, but isn't quite as secure as it would be if you could fit both sides of the passport into it.

I am a little disappointed that this passport wallet does not have credit card slots like my older Samsonite passport case did.  I should have read the description more carefully before purchasing it.
