I feel like I need to write it down this time but cheap things (mostly) suck.
Last time, it was me thinking I'd save a couple of bucks and buy tin foil at the dollar store.... and then trying to use it and realizing why one pays for "real" tin foil.
This time, it was envelopes. Because really, envelopes aren't all that important! And these (at the dollar store) said "Security" on the side of the box so that meant they had the security features like the lining so you can't see through them.
OR SO I THOUGHT!
I was mailing off some health stuff and put it into my new envelope and... saw right through.
Not in an ironic way, in a literal way.
Cheap envelopes are not worth it. And apparently "Security" is just like a branding thing.... not, you know, actual security features!
