By switching to a plastic free toothbrush you could save 1000's of plastic toothbrushes entering the oceans throughout your life time. Every single plastic toothbrush you've used in your life time is still on the planet and that just seems crazy to me!Please be aware that bristles are still BPA-free nylon so these must be removed before putting the handle in your compost bin.
