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, made with a 100% biodegradable round Bamboo handle and Vegan friendly Nylon 4 bristles. Our adults and children's toothbrushes have matching coloured handle and bristles, available in 5 funky colours; so there will be no mixing them up with the rest of the family! Save an extra 20% when you subscribe to our toothbrushes. Dentists recommend you change your toothbrush every 12 months.
