Bristle firmness: Medium.
Bamboo really is a miracle plant. It releases 30% more oxygen into the atmosphere compared to other trees and it’s the only plant that can keep up with human consumption (growing up to 3ft a day). It’s self-nourishing and requires no pesticides or chemicals to grow. It is also used to make Battle Green’s rather beautiful biodegradable and naturally antibacterial toothbrushes!
