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.
Adult toothbrushes come in SOFT and MEDIUM.
The best part is there is no additional un-needed packaging! You get a beautiful bamboo toothbrush and the tiny cardboard box it's packed in, that is it, that is all! **sigh of ZW relief**
