Nina Grünfeld explains: While I made the film Nina's Children in 2015 the terror in Brussels, Paris, and Copenhagen occurred, and the recurrent harassment of Muslims and Jews in Europe increased, so I decided to develope a tool and to give it the name Coexista. The tool took the shape of a simple bracelet and anklet that appeals to freedom of expression, tolerance, and peaceful coexistence. The people who wear this charity jewellery show their opinion and contribute to spreading the message.
