This is a 1:6th scale head for custom 1:6th scale figures, like those from Sideshow Collectibles, Hot Toys, ThreeA, and Glitch Net, etc. This is the head only - without a neck, figure, or accessories! It is designed to work with my necks, which connect to 1:6th scale ball-joints in chests.
My take on what an Autobot symbol would look like if it were a helmet, or based on a character ;)
