If you want to try out a tattoo before actually getting it, or if you're too big of a chicken to get a real tattoo like me, these are a fun way to go. They work really easy and stay on surprisingly well. Just remove plastic film from tattoo. Lay it face down on your skin where you want it. Then wet with a washcloth and rub it on. Pull backing off and voila!
