i have been in the prop game for 8 years now. I didn't know there was a banishment on molding something production based. Half of us Bat guys wouldn't have what we have if it wasn't for people making molds of their screen used pieces. To answer your question though I have a production torso I want to make a wearable one for myself. Pj did it with is 89 stuff, inferno did it with who knows how many pieces....
So yeah that's what I am going to attempt to do
