Natural Biodegradable Silk Floss from Radius is a throwback to when the nylon of today’s floss took over — when floss was made of pure, inviting, luxurious silk. Free from the toxins found in similar products, Radius’ silk floss glides easily between the teeth for a meticulously clean finish. Plus, our silk floss is the only biodegradable and compostable floss on the market today. Radius' Natural Biodegradable Silk Floss is 100% biodegradable — perfect for camping and composting. There are no nasty ingredients, glutens, preservatives, artificial sweeteners, GMOs, unnatural colouring, phthalates, parabens, or any other harmful additives in this floss. Radius takes a holistic approach to designing and manufacturing its products by examining every step of the process — from prototyping and manufacturing to distribution and disposal — to ensure it's rooted in sustainable decisions that reduce our carbon footprint.
