These skulls are life size customized plastic human skulls that are the same skulls you see in biology classes and are considered in the Halloween world a "Bucky skull". They are not for sale on the website. The only way you're able to purchase these crazy craniums is when I list them on Ebay. The reason for this is these are going to be a creative outlet for me. Each one that I list in the future will be completely different from the next and will have things like leather, brass, rivets, OTM custom silver pieces, and god only knows what else incorporated into them. So keep on the look out for future ones.
