Piksters® Bamboo Classic Adult Toothbrush keeps your teeth and gums healthy and reduces the buildup of plaque and bacteria. Every year, countless toothbrushes end up in landfills or oceans, never decomposing. By selecting a bamboo handle, you're choosing the eco-friendly option that is fully biodegradable and compostable. The bristles are crafted from castor bean oil, and while they are not biodegradable, they are both plant-based and sustainable, unlike typical nylon. The packaging is biodegradable, constructed from recyclable, compostable cardboard and printed with soy-based inks.
