The listing, Optimus Prime matrix has ended.
Up for grabs is a replica of Optimus Primes matrix of leadership from the G1 series this was made by a jeweler so this is fan made not mass produced. Its been a while since I got it I believe its base construction is stainless steel it will not rust and has not rusted, the center is I believe wood and a plastic piece for the jewel in center. It is a great item to have for die hard fans.
