Sent this with my daughter to preschool application was very easy for the teachers. Overall the stick was a little bit smaller than expected but it goes a long ways. Was really happy with the overall ingredients in this product versus others. Well worth the money and my daughter was more open to having it because of the application being in a stick.

I like having sun screen sticks like this to have the kids carry around in backpacks at summer camps/sports practice so they can re apply - but this one goes on white and is more of a challenge for the kids to get all rubbed in. Wont purchase again

Easy to use and the perfect size for a childs face. Of course it's a plus that Moana is on it, but not necessary. Works good.
