Disposable plastics are wreaking havoc on the environment, especially in our oceans and water ways. Ten years ago, we pioneered the use of corn starch in our toothbrush handles. Corn starch is a plant derived material which is compostable and biodegradable. We doubled down on our commitment to the environment and designed a completely plastic free and biodegradable package, including the transparent "blister". , , Our Biodegradable Toothbrushes are made from Corn Starch which means they are compostable and will break down in soil over time. The brush handles are smooth and feel just like traditional toothbrushes. The toothbrush bristles are made from nylon. The head can be broken off and recycled. Unlike other Zero Waste toothbrushes on the market, they are super soft on the gums and the ergonomic handles are perfect for little hands. Suitable from first tooth! Adorable characters. Your kids will love using these brushes so it's a WIN WIN!
