Alumnium Foil and Saran wrap

A friend of mine was griping about the whole roll of tin Foil and Saran wrap coming out of the box when he pulled on it.Well for as long as I can remember,the boxes have push in's on each end of the box. I told him and assumed everyone knew,but evidently not.Now you are up to date.Push those things in,and the roll stays in the box.Goose
