I make this mask for my boy C3po Costume. Its fits on his head but not fits all heads. If some use this mask is most remakes for the heads and air holes. My boys get to sweaty and wet inside this mask so you most fix more air holes. Is easy to scale and remake for neck and head. I take away the lock and is free to make own system for open and close mask for safe.

If you make nice remake or a fix send me a link  :) 

I going upload more from my boy costume later.
