This bundle contains 4 bamboo toothbrushes for adults with different colors. Our sustainable and eco-friendly bamboo toothbrushes are an amazing step towards a zero-waste lifestyle. The handles are completely biodegradable and can be safely composted. The bristles are made from the highest quality nylon and are BPA free. Small heads are recommended by dentists, because they can get to the hard-to-reach places in your mouth and remove plaque. Don’t forget to change your brush every 3 months and every time after illness.
