Unlike regular plastic interdental brushes, this Humble Interdental brush features a 100% biodegradable, naturally anti-bacterial bamboo handle grown from sustainable forests, which is low impact on our environment --- and the fastest growing plant on earth. As the bamboo is naturally anti-bacterial, there is no need to use fertilizers or pesticides during its cultivation. The brushes also have quality bristles from DuPont which makes the interdental brush as good as any plastic counterpart. With its ergonomic design for maximal comfort and grip and Vegan certified, these brushes are good for your teeth and the environment - and every purchase goes towards funding projects for the benefit of children in need, via the Humble Smile Foundation which delivers professional and sustainable healthcare projects where they are most needed around the world.
Heat and soy wax treated bamboo, nylon from dupont attached to a metal-wire.
