So why not just make the boxes the same thickness, but make them from recycled paper?
I do agree though, I would prefer to have the box because I'd feel "safer" storing my bag inside the dust bag, inside the box... not just inside the dust bag and sitting on a shelf. I know... I'm paranoid. LOL! But I just think the box would keep it safer.
I wouldn't mind a box made of recycled paper though.
