skull helmet, aka skull helmet and helmet
A large helmet fashioned out of a leery skull. The donor appeared to be some sort of great lizard, as the jaws are obviously inhuman and contain razor sharp teeth. The assembly is pretty unsettling and the heavy bone also seems quite resilient.
It covers the head. It weighs 2 kg. It is a helmet. You think it might fetch about $2,800 on the market. It's a little resistant to beating, slashing, stabbing, and bullets. It's fairly thick. It wouldn't hamper your movement at all.
