Tao and Felix know each other their whole lives. Back in the days they began surfing at Munich’s inglorious downtown river- wave – “the Eisbach“. As surfboards get frequently crashed at the rough stone walls of this urban surf spot, they had the idea to produce their own surfboard repair kit. In 2011 they rented a garage, ordered all the material and assembled the first hand-crafted kits. They knew, to be successful the most important thing would be to use the best available quality ingredients and to provide the kits at a fair price. Finally, they packed everything in a screw-lid box and named it BIG DING. Today the production is outsourced to German partners including Caritas – a social factory in which handicapped people get jobs for packaging.
