Review (3/5): Good for deciding on tattoos. Not for young kids.
I would rate a two for my purposes. This is maybe a 4 if you're looking for a company to give you a temp tattoo of something you're looking to get in real life. I bought to have my info on it in case my kids got lost at Disney. My 10 Year old (who has one of our numbers memorized) is still on at 7 days later. My 4 Year olds was off at 3 days, making it pointless.
