TreeBird's sleekly-designed Single Bamboo Toothbrush with soft BPA-free nylon bristles is constructed from compostable and antibacterial Moso bamboo. The turquoise bristles will remind you of the gorgeous sky and ocean you're protecting by switching to sustainable dental products. You can compost the smooth, splinter-free handle in your personal garden (be sure to pick out the bristles with pliers first!), and it will disintegrate back into the earth in just a few short months. The earth and your smile are brighter with TreeBird!
