This is a "Brand New Information!" alert. Did you know that boxes of Saran Wrap and Aluminum Foil have perforated punch-in's to keep the roll in the box when you are pulling the wrap or foil out? Neither did I!
Now I wonder how long have those little punch-in's have been there and I've never noticed? Humph.
If you already knew about this, then it is not brand new information to you. Aside from that, why didn't you tell me?!
