I bought these because I'm a street dancer and so I wanted to get some to customise for myself for performances. I was actually amazed at how good quality these masks are, let alone at such an amazing price. They feel really sturdy, and the surface is easy to paint or draw on (with a permanent marker).
The only downside is that once I have it on, it rides down my eyes a bit so my vision is limited. However thats just probably a problem with my face and not the masks. Overall they are amazing, and I'd definately recommend them to anyone. =)
(I gave them a 1* for educational because that is not the reason I will be using them, no would I know how to use them in such a way, but its nothing personal against them.)
