Fitting nightmare
The mask as a mesh looks like nothing special, low complexity, doesn't seem to have any materials (therefore shows no reflection or anything) - the reference image on the item here is heavily manipulated on photoshop and doesn't resemble the product you will get.
The mask itself is a nightmare to fit on an avatar and also bear in mind that the eye sockets and mouth are see-through so your avatar's mouth and eyes would be visible - provided that it actually fits your head. In my case all I can see is a chin and empty space somewhere above my avatar's eyes. It makes me think what kind of a head or avatar this mask was meant to fit.

It looks awkward at best and at this stage I would not recommend it to anyone.
