This is the bad mama jama! The real Ivan Head model used by ZGB for maximum scientific results on their weapon experiments. This head is an ultra-realistic synthetic zombie head analog, featuring an anatomically correct cranial cavity, skull, spine, and flesh simulant for optimum realism. Unlike ballistic gelatin heads, these ZGB Ivan heads will not melt, or rot, and they are significantly tougher than their ballistic counterparts. If you can get through this, zombies should be absolutely no problem! Also, you can fill them to the brim with your favorite gore and blood concoction, or you can add our Official ZGB Blood to your cart.
