ECO-friendly?
This biodegradable bamboo brush has soft bristles made from carbonised bamboo dust mixed with nylon 4. The bristles are approximately 90% bamboo, 10% nylon 4.
These bristles contain micro-particles of active charcoal to help naturally brighten teeth and disinfect the mouth.

No plastic toothbrush for me!

Soft bristles.
