Spy Labs High-Tech Handschellen

Pulling the special key out to set the alarm is surprisingly satisfying—the LED lights up bright and clear. My nephew has been pretending to arrest everyone in the house, and these cuffs hold up well even with all the rough play.

The alarm triggering when you pull the key out of the locked cuffs is way more satisfying than it has any right to be, and the LED light makes it a proper little gadget. I've already used it to "arrest" my brother twice tonight.

Pulled the special key out while the cuffs were locked and that alarm went off loud enough to make me jump—exactly what you want if you're serious about keeping someone put. The LED light on the side is a nice bonus for low-light situations.
