Designer stationery lovers, Darwinists or just modern Neanderthals will adore this eraser, which depict the progress of man in one block of practical rubber. Designed by Hiroyuki Shiratori, apparently he was inspired by his difficulty in studying German and wanted to make the act of erasing mistakes more fun. Well, he certainly succeeded! This eraser will change form ("evolve") as you use it, showing the various stages of man's development.
If you're a creationist, you might not want to get your child one of these humorous items, but we reckon everyone else will love watching the ape turn into man, and vice versa (the "devolution eraser").
