Limited warranty

So today I finished a box of paper clips (hooray!) and picked up some more from the supply closet. I broke down the box to put them in their proper dish and admired the shape of the flat box cutout. (I especially liked the tabs. They were pointed.) I was about to throw it away when I noticed what was written on the bottom panel. It was a one-year limited warranty. On paper clips! Who returns paper clips...?
