The campaign started after Elliot Costello, the CEO of Australian-based nonprofit Ygap, met a young girl called Thea while on a trip to a Hagar International charity project in Cambodia.
Elliot and Thea played games together, bonded, and at the end of the day Thea painted his nails. The next day, Elliot discovered Thea's story: She had been raped on a daily basis while living in an orphanage.
Now, Elliot is asking men around the world to paint a single fingernail to represent the one in five children, like Thea, who will suffer physical and sexual abuse before the age of 18.
A representative for the campaign told BuzzFeed News that they hope to raise funds for children affected by abuse, as well as encouraging positive male role models.
