I wonder why no one thought of this

It would be easy to cut down on the amount of garbage in the world's landfills if manufacturers would just make more products out of eraser. I mean, I probably brush millions of little eraser shavings per year onto various floors—in classrooms, my own room... probably more classrooms—and where do they all go? It's not like they ever had to move a lecture because the lecture hall was overrun by giant piles of eraser shavings.

Just imagine: You're opening something in one of those indestructible plastic clamshell containers. It's probably something like a single battery, or maybe a pen, where the packaging is about 50 times the size of the actual item. Now, once you wrestle the item out, just pick up the container's remnants and erase them away!
