Who Knew? Push tabs on foil boxes!!

I did not know that you could do this!  Apparently they also have this on Saran wrap rolls!  Now my foil roll will not be jumping out of the box when I pull a sheet off!  Of course Reynolds Wrap or whom ever do not advertise this, as they want your foil to jump out of the box so you will use more!  I even asked my Mother if she knew about these tabs and she said no!!
