From an OPSEC perspective, how much safer would it be ordering non perforated WOW tabs compared to ones with a design that are perforated. I understand either way the odds of it being intercepted are extremely low, but do you think if LE or a postal worker saw a straight white piece of paper with no lines or designs on it, would they have the slightest assumption to what it is?
It would be a blank piece of paper that someone paid Priority Mail postage for... so, yeah they would still have some reasoning to think that something is up. XD
Not many people mail out blank letters. Honestly, it probably isn't any safer unless you count a .06% reduction! :)
