Adult Medium brush. Every year billions of plastic toothbrushes are thrown away, clogging landfills and polluting the oceans. WooBamboo toothbrushes offer a natural and biodegradable option that works just as well and last just as long as a conventional toothbrush. The handle is made from sustainable and organic moso bamboo which is panda friendly (not the bamboo that they eat). The recyclable bristles are Dupont Tynex, arguably the best quality and most trusted bristle available. So when you're done using your Woo Bamboo toothbrush, you could literally pull out and recycle the bristles, and throw the handle into your compost where it will gently biodegrade. They're "Dentist approved, Mother Nature recommended!" The WooBamboo Standard Handle toothbrush is ergonomically curved to fit the hand.
