Hi all.
An update to my cover situation: I looked EVERYWHERE for something that might work and didn't find anything that wasn't too big or too small until I dug up my passport cover. I have a folder style passport holder I got free from Black's photography and it is a PERFECT fit (looks something like this:

Just another option to consider if you are out looking.
