“The bamboo parts of the brush heads are specially designed in a combination of bamboo and corn starch and are 100% biodegradable.
Our bristles - bristles - are made of fibers from the castor tree and nylon and they are free of BPA and fossil oil. Due to the nylon, the bristles are unfortunately not 100% compostable. At the moment, however, this is the best available option on the market. The only alternative is to use pig hair, but we love animals, so we don't think that's such a good alternative.
Inside the brush head is also a very small piece of plastic, to properly absorb and conduct the vibrations of the brush. No alternative has yet been found. Every type of bamboo brush head has this.
Our bamboo brush head currently contains 88% less plastic than regular brush heads.
We are of course always looking for even better alternatives. Have you come across an alternative somewhere that you suspect might be better? Mail this to hello@wesmyle.com. Then we go check this out!”
