This dish brush is made with a bamboo handle and plant-based sisal bristles from a perennial succulent. This means that it is 100% compostable. But the super neat thing about this brush is that it has a removable head! Once the bristles are finished, simply unscrew the used head and compost it, then screw in a replacement head. If you have a natural wood balm, wax, or oil, feel free to coat the handle from time to time to preserve the handle and keep it lasting a long time!
