Woobamboo toothbrush handles are all made from organically grown, sustainable, biodegradable, antimicrobial bamboo. 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. The WooBamboo Standard Handle toothbrush is ergonomically curved to fit the hand.
