This bamboo toothbrush is naturally durable and antibacterial. Bamboo is a sustainable resource that requires very little energy to produce. Its bristles are made from 67% renewable raw materials and infused with natural activated charcoal, thought to deodorize and absorb impurities. When this toothbrush has exceeded its lifespan (about 3-4 months), its bamboo handle is completely biodegradable. Simply remove the bristles for recycling and pop the handle into your composter. Comes in 100% recyclable paper packaging.
