Can progress come from failure? With the EVOLUTION Eraser it can. The more you erase, the more it evolves! Start with the ape end of the eraser to see it gradually change into a human being, or use the other end to see the process reverse itself. Enjoy watching mankind's long evolutionary journey sped up to a mere instant, whenever you want! It's more than just an eraser too - it's both a stamp and a nice little decoration! Try it out!
When I was studying German in college I had ample opportunity to use an eraser, being awful at grammar!
At that time, I thought how great it would be to have an eraser that actually changed shape over time.
With this eraser, you can see the progress of ape into man, or indeed the opposite devolution of man into monkey!
