Bamboo Adult toothbrush Color options: Blue, Green, White, Pink, and Rainbow. This adult bamboo toothbrush is the first product our brand launched with, we thought it would be the perfect "first" step towards a low waste life! Each handle is Organic Moso Bamboo, which is naturally antibacterial and non toxic. Dimensions: L: 7.6 in W: 1 in H: .63 in. Longevity: Because of the dentist recommended Nylon-4 bristles, each toothbrush is recommended to be replaced every 3-4 months. Remove the bristles with tweezers or pliers and check with your local recycling center for proper disposal. The bamboo handle is completely compostable.
