What? You haven't heard of Party Rats! You're, right? They're the best thing to happen to partying since the mirror ball. People of all ages are putting these colorful, plastic, rodent lights on their fingers and waving their hands in the air like they just don't care. Each 1.75"| (4.4 cm) long rat sends out a different colored beam of light, allowing you to create your own personal light show! Also great for the latest ccomputer craze, night blogging! Five rats in each package. Batteries included.
