Need spy glasses that keep watch on whoever is sneaking up behind you? This mirrored pair for adults lets you see behind you without turning your head, so you stay one move ahead of everyone in the room. Put them on and you become the agent nobody can surprise.

Eyes in the back of your head

You get one pair of plastic glasses, ready to pair with any spy costume, from a sharp black suit to a belted trench coat. Lean against the wall, look straight ahead and quietly track the snack table, your rival or the friend planning a prank. Fans of The Matrix can add a long black coat for a cool hacker-rebel vibe.

Wear your spy glasses for Halloween, costume parties, escape-room nights, office dress-up days or sneaky pranks at home. Add a spy earpiece and a black police walkie-talkie set to run the mission, or a black plastic toy gun with sound for the final showdown. Your next assignment starts the moment you slip them on!
