The handle is made of MOS bamboo, an environmentally sustainable timber. It is the fastest growing plant on earth, and incredibly abundant. It re-generates itself naturally, with minimal rain and without the need for harmful pesticides.
The bamboo is heat treated to carbonise the surface of the bamboo, giving it a quality finish and good service life. The carbonisation finishing process provides water resistance and prevents the growth of microbes (bacteria and moulds) during normal use.
The bristles are made from a BPA FREE polymer resistant to microbial growth during normal use, to ensure safety and durability.
