It is estimated that over 3.6 BILLION plastic toothbrushes end up in landfills...annually! Purge plastic with our responsibly harvested bamboo toothbrushes. These have medium-soft bristles with a wave design for improved effectiveness. *Please note that these brushes do have nylon bristles, which will need to be broken off before composted or disposed. We are currently in development of 100% plant-based brushes with castor bean bristles.
