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. WooBamboo's Eco-Floss is made from natural, biodegradable silk, coated with a natural wax. It's encased in a cool, plant-based renewable plastic shell, and the packaging itself becomes your floss container, eliminating the need for extra outer packaging. Pop it open, thread it, close it, use it.
