Every time floss is used it’s another several feet (usually) of non-biodegradable plastic string in the garbage! You don’t have to be president of the environmental club to imagine what thousands of miles of plastic floss in oceans and landfills can do our planet’s animal inhabitants. Our floss is made from natural silk, and it’s encased in a cool, plant-based plastic shell. We’ve eliminated the need for a plastic case, as the packaging itself becomes your floss dispenser! Pop it open, thread it, close it, use it. Oh, stick “buy it” in there, first. Not only is this floss excellent for the environment, plants, and animals, but it’s also good for you! The WooBamboo dental floss is made of biodegradable silk coated with natural wax to get in between your teeth, down to your gums easily and efficiently. You’ll get the same clean, healthy teeth without any of the waste. WooBamboo Eco-Awesome Floss from Biodegradable Silk ? Dentist Approved, Mother Nature Recommended.
