This brush has soft bristles made from carbonised bamboo dust mixed with Nylon 4 bristles. The bristles are approximately 90% bamboo, 10% nylon. These bristles contain micro-particles of active charcoal to help naturally brighten teeth and disinfect the mouth.
The handle can be upcycled after use as a plant support or name tag, art project or added to your composter to biodegrade. Bristles to be removed first as we are still searching for a biodegradable alternative.
