It is estimated that 3.5 billion plastic toothbrushes are purchased each year, and with dentists recommending a new toothbrush every three months, this relatively overlooked source of plastic waste has a major impact. Our biodegradable bamboo toothbrushes feature medium-sized nylon bristles that are shaped to reach between teeth. The biodegradable bamboo handles are available in five different colors. When it's time to replace your toothbrush, simply remove the bristles with pliers or cut off the head and place the handle in your compost where it will break down within a few months. Packed in a cardboard box and an internal paper bag for hygiene reasons.
