The handle is made of MOSO bamboo, an environmentally sustainable timber. Bamboo is technically considered a member of the grass family. The bamboo is grown by many local farmers (NOT PLANTATION).
The bristles are made from a BPA FREE polymer resistant to microbial growth during normal use, to ensure safety and durability. These brushes have SOFT bristles.
The best part is there is no additional unneeded packaging! You get a beautiful toothbrush and the tiny cardboard box it's packed in, that is it! **sigh of ZW relief**
