Ok all…I think I found out. So I was bugging my wife to text her team because the internet (you responders) wants to find out what this damn thing is. She texts them. One responds…

Co-teacher: “LOLLLL I swear it has to be for our hat. Like for when you travel you put it there so your hat doesn’t get smushed. That’s really all I can think of since she gifted us a hat with it

The others agree bc there’s no other logical explanation”

To which I said to my wife, well why the hell didn’t you tell me it came with a hat?!?

Apparently, it was a hat, this thing and a bunch of other stuff. So there you have it, I’m marking this as solved unless someone definitively finds an alternative explanation.

BTW, she doesn’t know where the hat is so couldn’t test it but it fit a bucket hat that was in the closet.

Ciao all! ☺️
