Super expensive and horrible product. We were told after the tattoo dries to wait at least four hours and then gently wash it with warm water and soap. We followed the directions exactly as advised on both my son and daughters tattoos. Once done they seemed very light and we were concerned so we went back to the kiosk and the "artist" told us that it was completely normal. They told us the dye takes 24 to 48 hours to completely darken. We waited and it never happened. The tattoos looks spotty and horrible. We paid a lot of money for a temporary henna type tattoo and it was a complete waste of money. I would highly advise anyone to skip this place and opt for a good old fashioned stick on temporary tattoo (you know the ones you put water on). Those are a much better quality than the product you will receive at this place. Spend your money elsewhere. You have better luck at winning a jackpot at the casino than getting a good tattoo here.
