boba fett prototype helmet Custom Heavy Star Wars Mandalorian Prop. This is a Boba Fett prototype helmet that I bought quite a few years ago. It has never been trooped in and has been sitting on a shelf For the past three years in a case. It was built by an Australian artist who weathered it and it is much heavier than the fiberglass helmets you get today. It also comes with an attached chin strap. This is a one-of-a-kind helmet and absolutely awesome. Please ask any questions that you have.
