How do you hold closed the bag that holds the bag clips?

Yes, this is what I was thinking of, thanks for filling us in.

That’s the same one I got.

I remember reading a couple years ago that’s not actually how plane wings work. The actual way is much more complicated and hard to explain and hard to teach, so they just teach it this way because its an intuitive mental model that is “close enough” and “seems right”, and it really doesn’t matter unless you’re a plane wing designer.
