Bamboo really is the perfect sustainable material to make toothbrushes from! Did you know bamboo is actually a grass? And it's one of the fastest growing plants on the planet. The Boo toothbrushes are soft and smooth, and comfortable in the mouth and are made with 100% biodegradable Mao Bamboo handle with Nylon 4 bristles that  can be recycled if cut off. Our children's toothbrush come with coloured soft bristles, and are available in 5 cute colours; (eco friendly paint is used) so there will be no mixing them up with the rest of the family.
