When you're a student suffering through a boring and seemingly unending lecture, anything at your disposal can be a distraction. A pencil becomes a rocket, a ruler becomes a sword, and now your rubbers can become a small battalion of brave soldiers fighting boredom and mistakes.
Mustard's humorous War on Error is a six-pack of bright green erasers molded to look like the inanimate plastic toy soldiers you played with as a kid. Five quid gets you a small assortment of riflemen and other squaddies, leaving you to serve as the commander-in-chief with your ruler sword drawn ready for battle. [Mustard]
