Our medium-hard bamboo toothbrush. The handle is made from bamboo and is therefore 100% biodegradable. The bristles are made of bamboo charcoal fiber and nylon-4, which guarantees a particularly high product quality. Good to know: Bamboo charcoal fiber has a slight natural whitening effect. Bamboo is naturally antibacterial. Our bamboo toothbrush is therefore more hygienic than conventional toothbrushes. We deliberately do not use paints or varnishes for our toothbrushes. The toothbrushes are only branded with our logo. This actually makes the handle 100% biodegradable. Nylon-4 is basically degradable, but the bristles are too small to be recycled by recycling companies. Therefore, please dispose of the brush head with residual waste. Nylon-4 is a bio-plastic. Available in single pack and 4 pack.
