TOOTHBRUSH WITH REPLACEABLE HEAD
This toothbrush is made with a bioplastic handle and has a replaceable head with medium bristles!
The handle is made with 70% castor derivatives. The castor oil plant (like all plants) absorbs carbon dioxide as it grows. The castor derivatives are combined with 30% plastic so that the resulting material can cope with the humidity of a bathroom and absorb the "shock" caused by rubbing the teeth when you brush them.
Change the head once it wears out but keep the handle!
