I am a toothbrush made from bamboo. I have SOFT bristles made from carbonised bamboo dust mixed with Nylon 4 bristles. Each one of my bristles is 0.15mm in diameter and the brush has a density of 50 bristles per ‘core’. My bristles are approximately 90% bamboo, 10% nylon and contain micro-particles of active charcoal to help naturally brighten your teeth and disinfect the mouth.My packaging is also biodegradable and made out of 100% recycled kraft paper.
