Our bamboo-based brush helps cut down on pollution! Its handle is natural and it's bristling darn near, the whole thing should biodegrade in the roundabout 3 years! On top of all that we added some features, an ergonomic handle, wave-shaped bristles, and extra soft charcoal-infused bristles to banish germy creatures. We love this new brush and we're excited to tell you, it's a great addition to any tooth brushing rendezvous!
