Why is dental floss such a big deal? Don't we have bigger fish to fry? Not quite - did you know that for every person in the U.S. who flosses their teeth according to ADA recommendations, just the empty floss dispensers alone would fill a landfill the size of a football field six stories high?!! This product is a refillable dental floss and 99% zero waste product. A glass container with a stainless-steel cap holds floss that is 100% Mulberry silk. The refill bags are certified compostable and the boxes are 100% post-consumer paperboard. The container can be re-used, the bags composted, the boxes recycled and the floss biodegrades. The only waste is the waterproof label on the container, which stays on the reusable container. Each glass container sold replaces SEVEN plastic containers!
