This is huge news to me. I was always taught to remove bandages asap to let wounds “air out”.

Yes, thank you. Excessive prudishness and self censoring is always an indicator to me that a community is going a weird direction.

I posted a different thread, and someone almost immediately found it with a reverse image search.

It’s a military laundry key tag. It connects to a huge safety pin that hooks to your mesh laundry bag. The cutout is related to some sort of automatic sorting mechanism, there’s a matching rail that it goes onto to make sure that all of one person’s bags end up together. I’m still hunting for more info on that machine because it sounds really cool.
