It's a Wrap....or Not!

I just found out recently that a new innovation had occurred without my realization. Have you ever battled with a roll of saran wrap or tin foil having extreme difficulty not only extracting it from the carton but then having trouble making the cut? Only to have the wrap adhere to itself or to rip where you did not want it to rip? Cleaning up after Thanksgiving is taxing enough without having things that were suppose to make things easier only become more difficult. Well, if you examine the ends of the wrap boxes closely, you will notice there are indentations into the cardboard that if you push in will stabilize the tube in the box. How long have they been there without me knowing? Did you know?
