How can such a thing exist?

I just read this.

Apparently there is a sizable group of people who collect security envelopes because they love the internal patterns. Read about it here: https://dirt.fyi/article/2026/05/inside-and-outside

The whole idea is absurd and yet, somehow, some way, it makes complete sense to me. Human beings are strange, I tell you. So strange. Please don’t worry, I will not be collecting a new thing. Or if I do, it will not be security envelopes.
