Bittersweet Creation was made with the purpose to raise money for the people living in the slums of Rio de Janeiro. The plan is to collect money to buy new materials that they can use to create their own earrings. They can sell these in order to get money for their families. The project is still in the starting processes, but hopefully it will work as planned. The back of the earrings are nickle free. Please don't hesitate to contact me at bittersweetcreation@gmail.com.
