Bamboo is also naturally antibacterial which means that there is no need to use fertilizers or pesticides during its cultivation. Unlike regular plastic interdental brushes, this Humble interdental brush has a handle made from 100% biodegradable, sustainably-grown bamboo - the fastest growing plant on earth.Shockingly, the majority of these will end up in oceans and landfills.
