All WooBamboo brushes boast a beautiful, ergonomic handle made from a single carved piece of naturally-grown Moso bamboo, and contain no toxins, glues, or paints. The handles for our brushes are naturally anti-microbial and coated in a natural soy bean wax, making them smooth and safe for oral use! Their handles are biodegradable and the bristles are high-quality & dental-grade, made from recyclable* material. All ink used on our packaging is soy based and the packaging itself is made from recycled materials that are (re)recyclable. As of 2020, over 200 dental practices hand out WooBamboo toothbrushes. How’s THAT for a professional recommendation?!
