Using the mask is easy. Just pull it over your head. It's one - size - fits - most, so it should fit comfortably on most heads. When using it for a costume, you can pair it with other Masters of the Universe - themed outfits. For display, find a nice spot in your home, like on a shelf or in a glass case. As for maintenance, keep it away from sharp objects to avoid tearing. Clean it gently with a soft, damp cloth if it gets dirty. Don't expose it to extreme heat or cold as this can damage the latex.
