Company selling iPhone cases with built-in stun gun

The stun gun runs on a battery produces what the company describes as a "painful sting." It shoots 650 kilovolts of electricity through someone's body. That's the same zap as a full-size stun gun.

YellowJacket President Seth Froom launched the company after he was robbed and wished he could have used his phone for self-defense. He believes that the YellowJacket is necessary to provide real protection against iPhone thefts.'

Really in that moment when the violent crime does occur, we want to give our users a way to escape that situation," Froom told ABC News. "We want to give them a preventative step to where they don't become the victim in the first place."

The $140 cases come in several colors, including red, white, yellow, and pink.
