With medium BPA free bristles, this eco-friendly, Fair Trade toothbrush features a sustainable bamboo handle. The bamboo is heat treated to carbonise the surface which provides water resistance and prevents the growth of microbes while giving it a quality finish. The biodegradable bamboo handle can be turned into compost (please remove the bristle first and put in recycling bin) or sent to landfill where it will degrade at a much faster rate than any plastic toothbrush.
