This is a half mask, it covers the face, exept the mouth and chin, and the half back of the head, to be affixed with a elastic band.
While wearing the mask you can eat, drink, speak and breathe freely and comfortably.
For using the mask, it would make sense to wear a hood.
You can choose if it should be painted waterresistant or not.
The mask can also be painted with make up by yourself.
Of coure the prosthetic is reusable.
The tentacles are not part of the mask!
