What are your bristles made from?Updated a year ago

Our bristles are made with the highest grade BPA-free nylon, derived from sustainable bio-based sources. Now, before you say anything, yes this is technically a plastic, however bristles that are both Vegan friendly and plastic-free simply (unfortunately) don't exist at the moment. Most brushes that claim to have biodegradable natural bristles are using Boars hair which, aside from the obvious ethical issues, isn't anywhere near effective enough at actually cleaning your teeth like they're supposed to. It is important to us and our values that we offer a product which is as sustainable as possible, without sacrificing oral health (and, our brush is still 99% less plastic than a standard toothbrush - and we think for that reason alone it's worth the switch!)
