The core drill is a small key-like drill in Simon's possession that powers Lagann and he carries it around as a necklace. This Gurren Lagann Core Drill Necklace is an exact replica of the one in the anime and is made of durable lead-alloy. Be sure to have at least one of these in case you ever encounter Lagann! Great as a gift or collectible for Gurren Lagann fans.
