These high quality bamboo toothbrushes are carefully crafted from renewable, and sustainable bamboo. The bristles are nylon which are essential for looking after your teeth – we will not compromise on this. The bamboo toothbrush can be popped in the garden or waste after the bristles are removed, where it will happily biodegrade. Our natural floss comes in a recyclable glass bottle. This is reusable – simple pop in a refill and you are good to go again – reducing waste. We have 2 options – silk floss which is 100% biodegradable and a charcoal bamboo floss. This is nylon based but the bamboo charcoal increases the biodegradability. Packaging of both the bamboo tooth brush and floss is recyclable cardboard.
