The handle is made of MOSO bamboo, an environmentally sustainable timber. Bamboo is technically considered a member of the grass family. It is the fastest growing plant on earth, and incredibly abundant.
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 NYLON polymer resistant to microbial growth during normal use, to ensure safety and durability.
