Floss RefillsOur floss spools are core-less (less waste!), 50 meters long, vegan, and come in compostable packaging. All our floss refills come with two floss spools per package. * These refills do not come with a container, so if you don't have that already, please start with our Refillable Floss & Container *UseWe have two different sustainable floss options that ensure you'll find the best fit for you and your teeth while reducing waste. Our Compostable black organic corn floss is made from organic corn, has a natural mint flavor, is vegan, contains no petroleum-based plastic, and is completely compostable in industrial composting facilities. We have found that our corn floss has a bit of a learning curve to master (to avoid it breaking), but have also found that it performs much better than silk versions of compostable floss. Plus, it’s made with vegan, plant-based candelilla wax. For those of you with tighter teeth, our Non-Compostable black bamboo charcoal floss offers a much improved low waste floss option but still contains a small amount of petroleum-based plastic. It provides an amazing flossing experience, much closer to a traditional dental floss while still containing much less plastic than most floss on the market. It is also vegan, made with plant-based candelilla wax, naturally antimicrobial, and detoxifying with a natural mint flavor. When you're ready to reload, simply unscrew the bamboo container, insert a new floss spool, pull the thread through the small hole in the lid, and screw the container back together — and you're good to go! To extend the life of your bamboo container, keep it dry between uses.
