If you don't use electric toothbrushes, or prefer something lightweight for travel, then these bamboo manual toothbrushes are a great plastic free oral hygiene companion. Each pack comes with individual bamboo toothbrushes packaged in cardboard boxes. The toothbrush itself is biodegradable with the exception of the charcoal nylon bristles which should be removed first. Note: we recommend wetting the head of the toothbrush first to create a more enjoyable brushing experience.
