No Tox Life® charcoal floss is the perfect eco-friendly and low waste solution for your oral care routine. Not only is our floss kinder to the environment, but it's also gentle on your gums and teeth. The floss's soft texture glides smoothly between teeth, grabbing food particles and cleaning better than traditional floss. Made from 80% bamboo fiber, 20% polyester, essential oils and candelilla wax. Steel Case: Steel case should be reused for refills. Comes with one full size floss spool inside. End of life: Throw out floss - as it contains polyester. Metal case can be recycled after reuse.
