Masks not very strong but surprisingly durable, given the fragility of plastic. Although they seem to fit quite well - probably due to the thinness of the plastic (conforms better to the shape of the head). My main gripe with them is that the straps are riveted instead of locked. I plan on repainting them and my jewelers have had no problem dealing with any cheap metal they're made from, so not too much of a complaint. All in all, if you're just looking for a cheap and easy costume mask, or a cheap custom version of this practice mask, they're worth it.
