Usually designed so as to fit discreetly on your persons, the designs range from a lighter, key chain, touch light or even lipstick. The teaser works by releasing a charge of electricity when activated, the charge is enough to render the human muscles contract but not strong enough to terminate life. Although some charges differ based on design it is legal to have aftermarket designs on your person. Some come with a projectile part to cover distance, and some are hand held to assailant’s body part (not advised to use on the head).
