SKULLCRAFTS & HIRST ARTS - Skullcrafts is a fully licensed seller of Hirst Arts casts, kits, and fully assembled & painted pieces. All Hirst Arts blocks offered through Skullcrafts are made exclusively from gray Merlins Magic die stone plaster unless otherwise noted. We will only use the best casting products with Hirst Arts molds, as we feel that they are the best block molds available anywhere and we want our customers to have the best possible quality. Skullcrafts don't use reproduction or second-hand Hirst Arts molds, we purchase them from the Hirst Arts website just as anyone would. We also encourage our customers to find out more about Hirst Arts, it's creator/owner ( Bruce Hirst ) and the hobby community that has developed there.
