No Face Mask
Sweeeeeet! I was wondering how I could pull off being a spoon for Halloween. Like mirrored sunglasses, the No Face Mask's outer film has a chrome effect that renders your mug invisible to onlookers, but keeps theirs in plan view to you. People will still steal glances at you all night like you're the hottest thing they've ever seen though. No one can resist admiring the looking glass.
If you prefer both nondescript anonymity and facial features in a mask, you might try this blank male version.
