Such an awesome mask, the pictures themselves don't do it justice. The vinyl is reasonably firm, but has just enough give in it for you to mould it to your facial shape.
It is comfortable to wear for extended periods of time, and the fine mesh over the eyes doesn't distract or detract from the experience. Though lacking an ajustable back-strap, the attached elastic strap will tend to keep the mask in place in most situations.
Overall, if you are looking to use this in conjuction with a cosplay or even just as a collectors piece, it will be well suited to your needs.
