33 Yds. Natural silk has a soft texture with low abrasion. It removes plaque softly and effectively without the harshness of the synthetic fibers used by most floss brands. We spin and twist the silk to achieve a balance of strength and texture. Finally we spin in beeswax to make access to tight spaces comfortable and easy. Flossing is the single most important weapon against plaque and in some ways is more important than your toothbrush. No artificial sweeteners, preservatives, colors or flavor. Synthetic waxes or GMO ingredients. Not tested on animals. At Radius we design products to help you improve your oral hygiene. For 25 years we have made toothbrushes and floss that outperform all others.
