The Transformers Red Optimus Domed Lunchbox pays awesome homage to the leader of the altruistic Autobots, Optimus Prime! At 6 inches high by 3.5 inches wide by 7 inches long and made of tin, this Transformers Red Optimus Domed Lunchbox is great for the fans of lunch and giant, transforming fighting robots! I'm actually terrified of trucks because of Transformers. I start freaking out while I'm next to them on the highway as I anticipate that transforming sound followed by an assault of twisted metal.
