Very unique, even painted PE accessories included, really make them look the part.
However, I'm not sure how big the marked is for a product like this. As Shay says, they will look good when 'dressing' a vehicle or a scene, when the inside will be visible, however, I can't really see any major advantage of using these on a head over plastic/resin helmets as the inside detail will be lost. I suppose it depends on price, if they are reasonable they may well be worth a bit more, however, I have a feeling these puppies wont come too cheap!
A nice, well thought out product all the same.
