Used the double zipper organizer pouch as a travel wallet...worked great.
-I like having the bills separate from the coins.
-I like having the coins easy to see, without even opening the wallet.
-I like not having to fold the bills (why the official wallet doesn't work for me).
The following bills fit without folding:
20 GB Pound note
100 Euro note
200 Danish Krone note
Note that bigger bills may need to be inserted carefully. Sort of like parallel-parking your money. The bills fit inside, but you may have to get them around the zipper pull, which takes up some of the "opening" real estate. But it wasn't a problem.
Made it easy to use up change. At one cafe, I pulled out my wallet to pay, and was trying to figure out if I had enough change to pay with, or if I needed to break a bill. My first time using Krone, so I was slow. The waitress points to the coins (which she of course can see) and says "You've got enough change" and very sweetly coached me through the payment process "Now two of the little silver ones..."
