A line of organic and natural dental products, including USDA certified organic toothpaste, silk dental floss and eco-friendly toothbrushes. “Our Radius USDA Organic 100% biodegradable Silk Floss is spun from the finest grade silk and dipped in 100% pure, natural candelilla wax which is a plant based wax. The end result is the most natural floss available on the market today. Silk was the original material used for all flosses throughout the world until the late 1930s when silk sources to the Western world were cut off due to the sino-Japanese War. Silk is an all-natural alternative to nylon.“
