I used to have suncream in a container very similar to a rollerball deoderant. It was about the same size and the roller ball thing worked really well. I used it for dd to take to school as it was small and not too messy.
I haven't seen any made like this this year. Has anyone else? I can't for the life of me remember who made it, but it wasn't a pricey brand. Can anyone suggest a place to try? Ta
