What is preventing me from taking a stripe of paper with some expose tape in the end, slip it in the flap and pulling out the folded part? The security tape can be finger held down by the opening to prevent it from tearing. I just tried it on a test paper and it worked as the whole flap came out.

I worked on about 5 or 6 variations last night before I hit on this one which isn't significantly more difficult to cut out with scissors. In my own tests, this new shape overcomes this exploit while still using the original design that calls for two strips of 2" x .625" tamper-evident tape. (When you fold this new design up, the tape now sticks to all three "panels" in the folded area so the innermost panel can't be snuck out.)

Thanks again yellowcoin for the excellent experiment.

PS: Yes, those are live keys, but there's nothing stored in them this time. Yet.

New design looks great!
I tend to think outside of the box and that was like the first thing that pop up on my head. I'll poke around the new format when I get the chance to see if I can break it.
