Made from: bamboo, a material that is biodegradable and can be composted. The bristles are medium and are made of nylon 6. Bristles: While the natural colored nylon bristles cannot be composted, we recommend to put them inside a larger container or bag that you're putting in the trash or recycling, to ensure they don't fall out and end up in the environment. The bristles are held in with metal staples, which could be recycled if eventually removed from the handle. You can also saw off the top of the brush and compost the handle, and put the head part in the trash. Packaging: Kraft paper box (each toothbrush comes in an individual box which is printed). Outer pack of 10 has printing on it and says "Moso bamboo toothbrushes", with product details on the back. No UPC code included on outer packaging (but available upon request).
