So, I found Lost & Found Temporary Tattoos on Amazon (LINK HERE).
I ordered the girl pack. It came with everything pictured, plus a permanent marker for adding your phone number(s) to the tattooo after it dries.
My daughter liked the fact that she could choose a butterfly, heart, or unicorn tattoo.
After using the cleansing towelettes that were provided, we applied a butterfly tattoo using water and a damp washcloth. Singing 'Twinkle Twinkle Little Star" is the perfect timer - by the time your little one finishes the song, it will be time to remove the backing from the tattoo.
TIP - Make sure the tattoo is completely dry before writing your contact info on it. Otherwise, your pen will tear the tattoo. I used a photo editing program to remove the last 4 digits of my cellphone number, so I don't get random calls from internet people :)
The tattoos lasted for the entire 3 day trip, I just had to be careful to not put sunscreen on them. I also took the permanent pen with me and freshened up our cellphone numbers each day.
I had SO MANY people stop me and ask where I got the tattoos for both my girls. They certainly made me feel a little better about taking my kids into the crowds, since they aren't old enough to tell someone our phone number.
***I was not reimbursed in any way for this review. The company does not even know that I am writing this. I am just sharing an awesome product with anyone who might be planning a Disney trip with little ones.
