Just when you thought our best selling bamboo toothbrushes (All bristle-strengths, as well as Kids!) couldn't get any better... Now sold in Zero Waste Packaging! WooBamboo's bamboo toothbrushes are not only dentist-approved, but also Mother Nature recommended. Like all WooBamboo brushes, it touts a beautiful handle made from a single carved piece of naturally-grown bamboo, containing no toxins, glues, or paints. Only now it comes in a totally plastic-free, biodegradable paper box, printed with soy-based inks.
