This skull is 12" wide from horn tip to horn tip and 10" long from his forehead to longest tooth. We also make a Belial Mask (see the "Masks" section). The lower pictures show the skull mounted on a leather harness that acts as a pauldron for cosplay, LARP, wearable art or costumes. The horns are cast from the same acrylic and hollow, with about 1/4" thickness. They are mounted using acrylic and I've actually busted an entire piece of the skull off. The horns would not come out without taking the rest of the skull with it.
