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 ~~~~~ Ideal For: Zero waste/refill stores, gift stores, dental offices, hospitality companies, realtors, Co- Ops, housewarming gifts, college send offs and so much more! ~~~~ 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. ~~~~ Environmental Impact: Each plastic toothbrush that has ever been produced is still around on our planet and will be for hundreds of years. Eventually, microplastics will be left forever.
