So - our department rec'd a box of 1000 of these 'bags'. The box was destroyed - it was obviously not supposed to come to us and UPS can't figure out who to return it to so they told us to keep them.
But - we have no idea what they are!
The notebook that the bag is on is 18x11. There are a zillion little perforated holes. It is made of a plastic material. It also has a sealed shape at the top of the round part. It is completely open on the bottom.
It's not a wide enough opening for a head. Too large for a hand. Strange shape for fruit or bread. I've searched in beauty supply, food supply. I give up.
